An input gear has 55 teeth and the output gear has 25 teeth. What is the gear ratio of these gears? Which gear turns faster and how much faster is it compared to the other gear?
An input gear has 55 teeth and the output gear has 25 teeth. The gear ratio of these gears is 2.2:1.
By dividing the number of teeth on the driven gear (output gear) by the number of teeth on the driving gear, the gear ratio can be calculated (input gear). The driven gear in this instance has 25 teeth, while the driving gear has 55 teeth, resulting in the following gear ratio:
For calculating gear ratio, divide by the number of teeth on the driving gear.
25/55 is the gear ratio.
45% or a gear ratio of 0.45
In a gear reduction system, the output gear rotates more quickly than the input gear. The gear ratio determines the speed differential between the gears. In this instance, the output gear has a gear ratio of 0.45, which indicates that it rotates 1/0.45 times faster than the input gear. output gear with 25 teeth turns faster, and it is 2.2 times faster than the input gear with 55 teeth.

The gear ratio of these gears is 2.2:1 . The output gear turns faster than the input gear, and it turns 54.55% faster than the input gear.
To solve this problem, we need to know the gear ratio and which gear turns faster.
We can start by finding the gear ratio.
An input gear has 55 teeth and the output gear has 25 teeth.
What is the gear ratio of these gears?
The gear ratio is the ratio of the number of teeth on the input gear to the number of teeth on the output gear. Therefore, the gear ratio is:
Gear Ratio = Number of Teeth on Input Gear/Number of Teeth on Output Gear
Gear Ratio = 55/25
Gear Ratio = 2.2:1
This means that the input gear rotates 2.2 times for each rotation of the output gear.
Which gear turns faster and how much faster is it compared to the other gear?
The gear that turns faster is the output gear, which has fewer teeth.
To determine how much faster it turns, we can use the gear ratio.
The gear ratio tells us that the input gear turns 2.2 times for each rotation of the output gear.
Therefore, the output gear turns 2.2 times faster than the input gear.
To calculate how much faster the output gear is turning, we can use the following formula:
Speed Ratio = Output Gear Teeth/Input Gear Teeth
Speed Ratio = 25/55
Speed Ratio = 0.4545
This tells us that the output gear turns at 45.45% of the speed of the input gear, or 54.55% faster than the input gear.

Deformation of a semicrystalline polymer by drawing produces which of the following?
[A]Decrease in strength in the direction of drawing
[B]Increase in strength perpendicular to the direction of drawing
[C]Decrease in strength perpendicular to the direction of drawing
[D]Increase in strength in the direction of drawing
The correct answer is: Deformation of a semicrystalline polymer by drawing produces Increase in strength in the direction of drawing.
When a semicrystalline polymer is subjected to the process of drawing, which involves stretching or elongating the material in a specific direction, it results in an increase in strength along the direction of drawing. This increase in strength is primarily due to the alignment and orientation of the polymer chains.
During drawing, the polymer chains are aligned and stretched in the direction of the applied force. This alignment leads to a more ordered and crystalline structure along the drawing direction. The increased crystallinity and alignment of polymer chains contribute to enhanced intermolecular interactions, resulting in improved mechanical properties, including strength, in the direction of drawing.

The grinder has a force of 400 N in the direction shown at the bottom. The grinder has a mass of 300 kg with center of mass at G. The wheel at B is free to move (no friction). Determine the force in the hydraulic cylinder DF. Express in newtons below.
The resultant force in the hydraulic cylinder DF can be determined by considering the equilibrium of forces and moments acting on the grinder.
A detailed explanation requires a clear understanding of the principles of statics and dynamics. First, we need to identify all forces acting on the grinder: gravitational force, which is the product of mass and acceleration due to gravity (300 kg * 9.8 m/s^2), force due to the grinder (400 N), and force in the hydraulic cylinder DF. Assuming the system is in equilibrium (i.e., sum of all forces and moments equals zero), we can create equations based on the force equilibrium in vertical and horizontal directions and the moment equilibrium around a suitable point, typically point G. Solving these equations gives us the force in the hydraulic cylinder DF.

semiconductors are materials that are neither good conductors nor good insulators
T/F
True. Semiconductors are materials that have a conductivity between that of a conductor and an insulator. They have a band gap that is smaller than that of an insulator but larger than that of a conductor.
This means that they can conduct electricity under certain conditions but not as well as a metal conductor. The conductivity of a semiconductor can be increased by adding impurities, a process called doping. This is important in the manufacturing of electronic devices such as transistors and diodes. In summary, semiconductors are a critical component of modern electronics and are neither good conductors nor good insulators.
Good conductors, like metals, allow electric current to flow easily due to their high number of free electrons. In contrast, good insulators, like glass or rubber, prevent the flow of electric current because they have very few or no free electrons. Semiconductors have a moderate number of free electrons and can be controlled to either conduct or insulate electric current, making them versatile for various applications.

A compressible fluid flows through a compressor that increases the density from 1 kg/m3 to 5 kg/m3. The cross-sectional area of the inlet pipe is 3 m2 and that of the discharge pipe is 1 m2. The relation between the discharge volume flow rate and the inlet volume flow rate is
Answer:
The relation between the discharge volume flow rate and the inlet volume flow rate is \(\frac{1}{5}\).
Explanation:
No matter if fluid is compressible or not, mass throughout compressor, a device that works at steady state, must be conserved according to Principle of Mass Conservation:
\(\dot m_{in}-\dot m_{out} = 0\) (Eq. 1)
Where \(\dot m_{in}\) and \(\dot m_{out}\) are mass flows at inlet and outlet, measured in kilograms per second.
After applying Dimensional analysis, we expand the equation above as follows:
\(\rho_{in}\cdot \dot V_{in} - \rho_{out}\cdot \dot V_{out} = 0\) (Eq. 2)
Where:
\(\rho_{in}\), \(\rho_{out}\) - Fluid densities at inlet and outlet, measured in kilograms per cubic meter.
\(\dot V_{in}\), \(\dot V_{out}\) - Volume flow rates at inlet and outlet, measured in cubic meters per second.
After some algebraic handling, we find the following relationship:
\(\rho_{out}\cdot \dot V_{out} = \rho_{in}\cdot \dot V_{in}\)
\(\frac{\dot V_{out}}{V_{in}} = \frac{\rho_{in}}{\rho_{out}}\) (Eq. 3)
If we know that \(\rho_{in} = 1\,\frac{kg}{m^{3}}\) and \(\rho_{out} = 5\,\frac{kg}{m^{3}}\), then the relation between the discharge volume flow rate and the inlet volume flow rate is:
\(\frac{\dot V_{out}}{\dot V_{in}} = \frac{1\,\frac{kg}{m^{2}} }{5\,\frac{kg}{m^{3}} }\)
\(\frac{\dot V_{out}}{\dot V_{in}} = \frac{1}{5}\)
The relation between the discharge volume flow rate and the inlet volume flow rate is \(\frac{1}{5}\).

Answer:
These formal systems state exactly what work is to be done, where and when. In many organisations, people doing the actual work are required to sign a permit to work document to confirm that they have understood all processes and guidelines of the system. Permits also serve as a means of communication between site workers and the organisation’s management.
However, they should not be mistaken as a replacement for robust risk assessment, which should happen simultaneously. Having a permit to work systems as part of organisational operations reduces the risks of losses or damage due to unsafe activities in a non-trivial work atmosphere.
These systems ensure that the correct jobs are entrusted to appropriate individuals and review or audit of conditions are also undertaken by experts or authorised personnel who have proven capabilities of undertaking the respective responsibilities. Permit to work systems also confirms that work is completed safely and the workplace is restored to its safe, original form for normal operations to commence.
