) While removing a wheel to change a tire, a driver applies forces P=111 N at the ends of two of the arms of a lug wrench (as shown in Figure Q2(b)). The wrench is made of steel with modulus of rigidity G=75 GRa Each arm of the wrench is r= 23 cm long and has a solid circular cross section of diameter d=1.3 cm (i) Determine the maximum shear stress in the arm that is turning the lug nut (arm A). (ii) Determine the angle of twist (in degrees) of this same arm.

(b) While removing a wheel to change a tire, a driver applies forces P=111 N at the ends of two of the arms of a lug wrench (as shown in Figure Q2(b)). The wrench is made of steel with modulus of rigidity G=75 GPa. Each arm of the wrench is r= 23 cm long and has a solid circular cross section of diameter d=1.3 cm (i) Determine the maximum shear stress in the arm that is turning the lug nut (arm A). (ii) Determine the angle of twist (in degrees) of this same arm.
