The velocity ratio of a chain drive is 10. The diameter of the input sheave is 38 cm and it is rotating at a speed of 22 rad⁄s. Find the diameter of the output sheave and its angular velocity.

How is heat transfer defined in an internally reversible process

Explain the process of predicting equipment failure?

Suppose that a wing component on an aircraft is fabricated from an aluminum alloy that has a plane-strain fracture toughness of 26.0 MPa (23.7 ksi).

Convection ovens operate on the principle of inducing forced convection inside the oven chamber with a fan. A small cake is to be baked in an oven when the convection feature is disabled.

As shown, a load of mass 10 kg is situated on a piston of diameter D1 = 140 mm. The piston rides on a reservoir of oil of depth h1 = 42 mm and specific gravity S = 0.8.

Just getting to your class is enough for showing up. A) True B) False

A completely reversible heat pump produces heat at a rate of 100 kW to warm a house maintained at 25℃. The exterior air, which is at 0℃, serves as the source.

A closed system undergoes a process in which work is done on the system and the heat transfer Q occurs only at temperature Tb. For each case, determine whether the entropy change of the system is positive, negative, zero, or indeterminate.

A scientist who is evaluating an ancient human skeleton for signs of vitamin and nutrient deficiency is conducting:
