Question

A uniform beam of length 18m and mass 30kg rests horizontally on support p and q, which are 1m from each end. A mass 2kg is placed at a point M where |PM|= 12m.
Find the magnitude of the reaction at Q.

Answer 1

Answer:

165N

Explanation:

The steps involved are balancing torque about point P, to find Nq

To find Np, you need to use and also, which is not necessary since question doesn't ask about Np

Answer 2

Answer:

165N

Mark forces for the beam and balance torque
