Question 437.
If the resultant couple of the three couples acting on the triangular block is to be zero, determine
the magnitude of forces F and P.
Given: F₁ = 150 N, a= 300 mm, b = 400 mm, d= 600 mm.
Answer 437.
Couple Pd acts downwards and couple F1b acts upwards
Balancing, Pd = F1b
=> P = F1 * (b/d) = 150 * (400/600) = 100 N.
Couple Fd acts to the left and F1a acts to the right
Balancing, Fd = F1a
=> F = F1 (a/d) = 150 * (300/600) = 75 N.
