Question
0.37 kg, A machine part as shown in following figure consists of three disks linked by light weight struts. Use mA mB = 0.51 kg, mc = 0.2 kg, a = 0.59 m, b = 0.82 m and c = 1.0101980004 m. Axis through disks B and C B mB C а Axis through disk A (perpendicular to plane of figure) A mc b mA a) What is this body's moment of inertia in kg/m2 about an axis through the centre of disk A, perpendicular to the plane of the diagram? Insert your answer correct up to at least a third decimal place. b) What is the moment of inertia in kg/m2 about an axis through the centres of disk B and C? Insert your answer correct up to at least a third decimal place. c) What is the body's kinetic energy in Joule if it rotates about the axis through A with angular speed w = 72 rad/s? Insert your answer correct up to at least a third decimal place.
