Question

Two particles of masses my = 1 kg and m2 = 2 kg are connected by a rigid rod of length L = 1.2 m and of negligible mass. The system rotates about an axis perpendicular to the rod and at a distance 'x' from the mass m1, and the moment of inertia of the system is I. Then

• A. I will be minimum at x= 0.8 m. 16
• B. I cannot have a maxima between x = 0 and x = L.
• C. Minimum value of I is 0.96 kg-m2.
• D. 1=1.44 kg-m2 when x=0.

Answer 1

Answer: (A), (B), (C)
