Answer:
Explanation:
The functions of the following are as follows:
1). Oil Rings:
- Regulates oil within cylinder walls.
- Helps to keep cylinder walls lubricated
- Prevent Heat transfer
- Reduce friction between piston and cylinder
2). Fly Wheel:
- It is used to store rotational energy
- It resist any change in rotational speed due to its moment of inertia
- It helps to control the orientation of the mechanical system
3). Timing gears:
- It provides synchronization in the rotation of crankshaft and the camshaft so as to provide proper valve opening and closing time during each cylinder's stroke(intake and exhaust).
Answer:
0.0375 ohms
Explanation:
The resistance of a material is the product of the resistivity of the material by the length of the material divided by its cross-section area.
Mathematically,
resistance= resistivity × length/area
In this case the resistivity of the material is the same, and the length is the same thus, assume a length of 1 unit, the cross-section area is the one changing
In applying the formula,
resistivity is r and length is l=1 unit, find the resistivity the material as;
resistance= resistivity * length /area
0.075=r*1/1.04
0.075=r*0.9615
0.075/0.9615 =r
r=0.078
use the r=0.078 , a length of 1 unit (assumed), and area of 2.08 mm² to find the new resistance
Resistance= resistivity * length /area
Resistance = 0.078*1/2.08
Resistance= 0.078 * 0.4807 = 0.0375 ohms
Point to note here is that the greater the cross-section area, the less the resistance.
Answer: I’ll send picture
Explanation:
Answer:
a) Internal energy
Explanation:
As we know that internal energy is a point function so it did not depends on the path ,it depends at the initial and final states of process.All point function property did not depends on the path.Internal energy is a exact function.
Work and heat is a path function so these depend on the path.They have different values for different path between two states.Work and heat are in exact function.
We know that in ir-reversible process entropy will increase so entropy will be different for reversible and ir-reversible processes.
