Answer:
The correct option is: (b) Shearing stress
Explanation:
The shear stress is described as the force that results in the deformation of an object or substance. It originates from the vector of the force component that is parallel to area of cross section of the object or substance.
The paired shear forces that produces shear stress, act equally on the opposite sides of the given object.
<u>In the given example, the stress produced when using scissors for cutting, is known as the shear stress.</u>
Answer:
a) 
b) 
Explanation:
From the properties of Super-heated Refrigerant 134a Vapor at
,
; we obtain the following properties for specific enthalpy and specific entropy.
So; specific enthalpy 
specific entropy 
Also; from the properties of saturated Refrigerant 134 a vapor (liquid - vapor). pressure table at
; we obtain the following properties:

Given that the power input to the compressor is 2 hp;
Then converting to Btu/hr ;we known that since 1 hp = 2544.4342 Btu/hr
2 hp = 2 × 2544.4342 Btu/hr
2 hp = 5088.8684 Btu/hr
The steady state energy for a compressor can be expressed by the formula:

By neglecting kinetic and potential energy effects; we have:



b) To determine the entropy generation; we employ the formula:

In a steady state condition 
Hence;


![\sigma _c = [200 \ lb/hr (0.2157 -0.2315) \ Btu/lb .^0R - \dfrac{(-3730.8684 \ Btu/hr)}{(40^0 + 459.67^0)^0R}]](https://tex.z-dn.net/?f=%5Csigma%20_c%20%3D%20%5B200%20%5C%20lb%2Fhr%20%280.2157%20-0.2315%29%20%5C%20Btu%2Flb%20.%5E0R%20%20-%20%5Cdfrac%7B%28-3730.8684%20%5C%20Btu%2Fhr%29%7D%7B%2840%5E0%20%2B%20459.67%5E0%29%5E0R%7D%5D)
![\sigma _c = [(-3.16 ) \ Btu/hr .^0R + (7.4667 ) Btu/hr ^0R}]](https://tex.z-dn.net/?f=%5Csigma%20_c%20%3D%20%5B%28-3.16%20%29%20%5C%20Btu%2Fhr%20.%5E0R%20%20%2B%20%287.4667%20%29%20Btu%2Fhr%20%5E0R%7D%5D)
