At full draw, an archer applies a pull of 130 N to the bowstring of the bow shown in the figure. Determine the bending moment at the midpoint of the bow.

Using Tall = 68 MPa and G= 27 GPa, determine for each of the aluminum bars shown the largest torque T that can be applied and the corresponding angle of twist at end B. Refer to Table 3.1. (a) (b) 45 mm 15 mm 25 mm 25 mm 900 mm B Check my work B The largest torque that can be applied at end B of bar a is N-m and the corresponding angle of twist is The largest torque that can be applied at end B of bar bis N-m and the corresponding angle of twist is
