QUESTION:
The A-frame is being hoisted into an upright position by the vertical force of F = 80 lb. Determine the moment of this force about the x axis when the frame is in the position shown. 30 15 6 ft y y x C A B F x z
ANSWER:Step 1 of 2
The following are given from the question.
The vertical force,
The moment about the can be calculated by using the below formulas,
Here, is the axis about which the moment needs to be calculated, is the position vector and is the force.
The axis vector is given by,
The position vector is given by,
