Card 1 of 20

How is a rigid body's distributed weight modelled when calculating moments?

A

The moment magnitude of an inclined uniform rod's weight about one end is mg(L2cos⁡θ)\boxed{mg\left(\frac{L}{2}\cos\theta\right)}mg(2L​cosθ)​.

B

73.5 N73.5\text{ N}73.5 N

C

Zero, because its perpendicular distance is zero.

D

As one downward force acting through its centre of mass.
