When drilling a hole in a table leg, a furniture maker uses a hand-operated drill (see figure) with a bit of effective diameter d = 4.0 mm. (a) If the resisting torque supplied by the table leg is equal to 0.3 N.m, what is the maximum shear stress in the drill bit? (b) If the shear modulus of elasticity of the steel is G = 75 GPa, what is the rate of twist of the drill bit (degrees per meter)?

asap please thank you
If length of rod is 2 m and a radius of 20 mm is made of high-strength steel. The rod is subjected to a torque T, which produces a shear stress below the proportional limit. If the cross section at one end is rotated 45 degrees in relation to the other end, and the shear modulus G of the material is 90 GPa, calculate the amount of applied torque?
Please do step by step
pls help me. thank u refer to the picture attached below.
A drill rod with a diameter of 10 mm is made of high-strength steel alloy with a shear modulus of 80 GPa. The rod is to be subjected to a torque T. What is the minimum required length L of the rod so that the cross section at one end can be rotated 90° with respect to the other end without exceeding an allowable shear stress of 300 MPa?
