The center of gravity of a right circular cylinder or cone is on the . . . . . .
a) center of mass
b) axis of symmetry
c) geometric center
d) origin
The CM/CG . . . . . lie inside the mass.
a) may
b) may not
c) both a & b
d) none of these
Torque/Moment of Force:
The turning effect produce in a body about a fixed point due to applied force is called . . . . .
a) moment of force
b) inertia
c) momentum
d) none of these
Torque Ʈ = . . . . . .
a) F × a
b) F × d
c) force × perpendicular distance from the axis of rotation.
d both b & c
Explanation: d = moment arm/ lever arm
The
SI unit of torque is . . . . . .
a) Newton metre
b) Nm
c) newton metre
d) both b & c
Explanation: not Newton metre because by Newton we mean scientist Albert Newton, and by newton we mean SI unit of force N.
