The three forces are perpendicular to the triangular plate. Find the equivalent

Question

The three forces are perpendicular to the triangular plate. Find the equivalent force-couple system, with the force acting at 0. Replace the three forces acting on the quarter-circular plate with an equivalent force-couple system with the force at point D. Use P = 400 lb and theta = 40 degree. When the three forces acting on the quarter-circular plate are replaced by an equivalent force-couple system with the force acting at point D. the resultant couple is zero. Determine P and the angle theta.

Explanation / Answer

As per Chegg rules 1 St question has to answered.

Equivalent force = (40+20+50)=110 kN

Equivalent force couple system at o .

= [(20*3)+(50*4)+(40*0)]=260 kN-m.
