1. Find the resultant of two forces of 40 lbs. and 50 lbs. acting at an angle of 60○ between them. 2. Three forces of 30 gms, 50 gms, and 60 gms respectively act at an angle of 120○ from each other. Find the resultant by rectangular-resolution (a) by making the 30-gm force lie on the x-axis, (b) By making the 60-gm force lie on the x-axis. 3. A weight of 100 lbs is supported vertically by two ropes, one making 60○ above the horizontal to the right and the other making an angle of 37○ above the horizontal to the left. Find the tension on the ropes. 4. By rectangular resolution of forces, find the resultant of the following forces: P=40 gms along the x-axis toward the right. Q=50 gms, 30○ above the horizontal toward the left; S = 20 gms vertically up; and T = 60 gms acting downward 30○ to the left of the vertical. 5. Each end of a wire 17 inches long is fastened, respectively, to two hooks lying on the same horizontal line. The hooks are 13 inches apart. A 26-lb weight is suspended in the wire at a point 5 inches from one hook. Find the tension of each part of the wire.
