Determine (a) the moment of the couple formed by the two 21-lb forces, (b) the perpendicular distance between the 11-lb forces if the resultant of the two couples is zero, (c) the value of ? if the resultant couple is 73 lb·in clockwise and d is 42 in. D 21 lb C 11 lb 11 lb 16 in ? A 21 lb B d (a) M_1 = lb·in. (b) d_2 = in. (c) ? = °

Step 1

A couple is formed by two parallel forces of equal magnitude but opposite in direction, separated by a distance. The moment of a couple (M) is calculated as the product of the force (F) and the perpendicular distance (d) between the forces. The formula is M = F * Show more…
