2. A Rotating shaft carries four masses A, B, C and D which are radially attached to it. The mass centres are 30 mm, 38 mm, 40 mm and 35 mm, respectively from the axis
of rotation. The masses A, C and D are 7.5 kg, 5 kg and 4 kg, respectively. The axial
distances between the planes of rotation of A and B is 400 mm and between B and C
is 500 mm. The masses A and C are at right angles to each other. Using either
graphical or analytical methods, determine, for complete balance:
a. The angles of the masses B and D from mass A
b. The axial distance between the planes of rotation of C and D
c. The magnitude of mass B​

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, 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 +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
