Question 87

what is the M.K.S unit of stress?

A) N/sq(mm) B) kgf/sq(m) C) kg/mm D) kg/sq(m)

Question 88

what is stress?

A) force per unit area B) force per unit length C) pressure per unit area D) pressure per unit volume

---

The force of resistance per unit area , offered by a body against deformation is known as stress. The external force acting on the body is called the load or force. The load is applied on the body while the stress is induced in the material of the body. A loaded member remains in equilibrium when the resistance offered by the member against the deformation and the applied load are equal.

Question 89

A) Ethane B) Methane C) Carbon dioxide D) Carbon monoxide

Question 90

In a compost pit, the heat of combustion of organic matter raises the temperature when decay is occurring rapidly. During decay, the temperature rises by?

A) 75 to 90?C B) 60 to 75?C C) 50 to 72?C D) 40 to 60?C
