Question

A machine part as shown in following figure consists of three disks linked by light weight struts. Use m_A=0.62 kg, m_B=0.98 kg, m_C=0.2kg, a=0.78m, b=0.21m and c=0.807774721m.

a. What is this body's moment of inertia in kg/m² about an axis through the center 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 centers 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 ω=32 rad/s? Insert your answer correct up to at least a third decimal place.
