Determine the maximum weight w the man can lift with constant velocity using the pulley system, without and then with the "leading block" or pulley at a. the man has a weight of 201 lb and the coefficient of static friction between his feet and the ground is μs = 0.61.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
