Q.3) The structure below is subjected to a set of forces as shown. a. Replace the given system by an equivalent resultant force and couple moment acting at point O. Draw the equivalent system. b. Reduce the equivalent system from part (a) into a simplest resultant (single force) and find the x- and y-intercepts for its line of action. Draw the simplest resultant and include a dashed line showing its line of action. F₂ = 220 lb F3 = 150 lb 60° -1 ft- F4 = 125 lb y F₁ = 90 lb 2.5 ft

Q.3) The structure below is subjected to a set of forces
as shown.
a. Replace the given system by an equivalent
resultant force and couple moment acting at point
O. Draw the equivalent system.
b. Reduce the equivalent system from part (a) into a
simplest resultant (single force) and find the x-
and y- intercepts for its line of action. Draw the
simplest resultant and include a dashed line
showing its line of action.
