For the state of stress shown, determine two values of oy for which the maximum shearing stress is 73 MPa. (Round the final answers to two decimal places.) ๆ oy The two values of oy are 48 MPa 50 MPa 56.9 MPa and- 172.13 - 4 MPa.

A 600 kg material is hung from the end of the horizontal bar BD as shown. Determine the stress on the rod AC if its diameter is 25mm. Use 2 decimal places in every solved values.

A flanged bolt coupling is used to connect a solid shaft 89 mm in diameter to a hollow shaft 100 mm in outside and 89 mm in inside diameter. If the allowable shearing stress in the shafts and the bolts is 66.2 MPa, how many 10-mm-diameter steel bolts must be used on a 191-mm- diameter bolt circle coupling so that the coupling will be as strong as the weaker shaft? Round off the final answer to three decimal places.

The steel shaft with two different diameters rotates at 4.6 Hz. The power supplied to gear C is 47 kW, of which 26 kW is removed by gear B. Find  the angle of rotation of gear A relative to gear Cif d = 56.3 mm, h = 66 mm, L = 4 m, M = 2.7 m, and G = 83.13 Gpa. Round off the final answer to two decimal places.

Answer for D

The cantilever beam AB will be installed so that the 60-mm side forms an angle β between 0 and 90° with the vertical. The 660-N vertical force P is applied at the center of the free end of the beam. Determine the value of β for which the normal stress at point a is a maximum and the corresponding value of that stress. (Round the final answer to two decimal places.)

Two forces, each of magnitude P, are applied to the wrench. The diameter of the steel shaft AB is 16.1 mm. Determine the largest allowable value of P (in N) if the shear stress in the shaft is not to exceed 88.06 MPa and its angle of twist is limited to 5.02˚. Use G = 80.89 GPa for steel and L = 449 mm. Round off the final answer to two decimal places.

Determine the diameter (in mm) of the largest circular hole that can be punched into a sheet of polystyrene 5.7 mm thick, knowing that the force exerted by the punch is 38 kN and that a 53-MPashearing stress is required to cause the material to fail. Round off the final answer to two decimal places.

round off only at final. four decimal places. with explain please.

The square steel plate has a thickness of 0.8 in. and is subjected to the edge loading shown. A) Determine the maximum principal stress developed in the steel. B) Determine the minimum principal stress developed in the steel.
