The idealized model of an initial design for a mechanism is shown below. The mechanism is attached to a rigid steel frame that may be considered to be ‘ground’.

For the loading condition with vertical load PV and horizontal load PH, and the linear actuator CD holding it in the position shown, determine the force required to be applied by the linear actuator and the reaction forces in each of the pin connections at A, B, C, D, E and F.

The load magnitudes are as follows:

PH = 1 + (7/10) kN

PV = 3 + (2/10) kN
