Figure Q9 (a) shows a simply supported beam with forces acting atpoints B and point E.Figure Q9 (a)a) For the beam to be in equilibrium, calculate the support reaction force atpoint C and at point D.

A skeletal diagram of a hand holding aload is shown in the upper figure. If theload and the forearm have masses of 2kg and 1.2 kg, respectively, and theircenters of mass are located at G1 andG2, determine the force developed inthe biceps CD and the horizontal andvertical components of reaction at theelbow joint B. The forearm supportingsystem can be modeled as the structuralsystem shown in the lower figure.

The load force is equal to the ____________, which is the force of gravity pulling an object downwards.
