Assignment 2

Q1: The arm OA is pin jointed at O, where OA =200mm. Determine the moment

of the force P about point O using:

A. The definition of moment.

b. Varignon’s theorem (rectangular components of forces).

c. parallel and perpendicular components of OA.

Q2: Determine the moment produced by the forces about point O.

Q3: In picking up a load from position B, a cable tension T of magnitude 24 kN is

developed. Calculate the moment which T produced about the base O of the

construction crane.

Q4: The 520N force is acting at point E as shown. Determine the moment of the

force about the AD axis.

Q5: Replace the system of forces in the figure with an equivalent force-couple

system at B. All dimensions in mm.

Q6: The pulley and gear are subjected to the loads shown. For these forces,

determine the equivalent force–couple system at point O.
