Armando turns his bicycle upside down to lubricate the chain as he turns the pedal. As he is about to turn the pedal to rotate the back tire a fly lands on the tire at a distance of 35.0 CM from the center of rotation. Amando turns the pedal the wheel starting from rest rotates faster and faster until it is rotating at 130 RPM within 3.00 seconds. What is the angular speed of the fly when the tire reaches its maximum speed?

I) a gas contained within a piston-cylinder assembly undergoes two processes, a and b, between the same end states, 1 and 2, where p1 = 10 bar, v1 = 0.1 m3 , u1 = 400 kj and p2 = 1 bar, v2 = 1.0 m3 , u2 = 200 kj: ' process a: process from 1 to 2 during which the pressure-volume relation is pv = constant. ' process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to state 2. kinetic and potential energy effects can be ignored. for each of the processes a and b, a) sketch the process on a p-v diagram. b) evaluate the work, in kj. c) evaluate the heat transfer, in kj.(ans : qb,12 = -65.0 kj)
