Concept explainers

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Question 7 The large piston of a hydraulic lift has a radius of 20 cm. What force must be applied to the small piston of radius 2.0 cm to raise a car of mass 1500 kg to the same level as shown? F₁ Small piston Large piston A₂ F₂
1. The piston hydraulic system can lift very heavy objects with a force significantly lower than that of direct lifting. Imagine a system in which the cross-sectional area of the piston is rectangular rather than a typical circle. The cross-sectional area of the small piston is 20 cm × 40 cm, while the cross-sectional area of the large piston is 2.5 meters × 6 meters. (a) How much force would need to be applied to the smaller piston to lift a 1300-kg car? (Ignore any height differences in the fluid) (b) Use proportional reasoning, order of magnitude, and/or related quantities sense-making techniques to determine if your answer to (a) is reasonable?

A proposal is made to use a giant spring in the bottom of an elevator shaft as a means of safely "catching" a falling elevator car. The car freefalls until it hits a spring, which is then compressed until the car stops. The car's loaded weight is 20.0 kN. The elevator will service 20 floors. Distance between floors is 4 m. The deceleration rate of the car should not exceed 10 g's as it is being stopped. (a) determine the requirements for the spring constant and the amount the spring will compress in order to catch the falling car in the worst-case scenario. (b) what do you think about this proposal? Is it practical?
A block of mass m, lies on the floor of an elevator cab of mass m, that is being pulled upward by a cable through a distance d. During this displacement, if the normal force on the block from the cab's floor has constant magnitude FN, how much work is done on the elevator cab by the force T from the cable (W, )? Express your answer in terms of m, m2, FN, and d. T m. Select one: W= Fyd(1 - m) W, Fyd( ) |3D Fyd(1 +m) %3D End(im

You are moving to a new place and to go faster, you are pushing with a force P, two boxes at the same time. Your homogenous box 1, on the top has dimensions I₁=1.5m, h₁= 1.6m and a mass of m₁=12kg Your homogenous box 2, on the top has dimensions 1₂=2.4m, h₂= 2.8m and a mass of m2=19kg The coefficient of static friction between the 2 boxes is $12 = 0.34. The coefficient of static friction between box 2 and the ground is SG2 =0.25. Analyze the 4 scenarios: • Box 1 tips on box 2. • Box 1 slides on box 2. . P • Boxes 1 & 2 tip together. • Boxes 1 & 2 slide together on the ground. ls + Gi + G₂ W₂ |h₂ T Find the minimum for P for all 4 scenarios (include FBD and equations of equilibrium for each scenario), and conclude which scenario will occur first and why. In the box below, enter the required force P to strat motion (either tipping or slipping) in N with one decimal.
