PROBLEM 3.107
When the couple M is applied to the link in a mechanism, the resulting
forces exerted on the link from a guide and the connecting links are as
shown. Determine (a) the values of M and a so that the applied forces
and couple can be reduced to a single equivalent force whose line of
action passes through points B and D, (b) the equivalent force.

Step 1

7 \text{ in.} + 2.2 \text{ in.}) - (20 \text{ lb}) \sin 30^\circ (1.1 \text{ in.} + 2.2 \text{ in.}) \\ &+ (40 \text{ lb}) (0.8 \text{ in.}) = 0 \\ M &= (20 \text{ lb}) \cos 30^\circ (2.9 \text{ in.}) + (20 \text{ lb}) \sin 30^\circ (3.3 \text{ in.}) - (40 \text{ Show more…
