The bearings at A and B exert only x and z components of force on the steel shaft. Determine the shaft’s diameter to the nearest millimeter so that it can resist the loadings of the gears without exceeding an allowable shear stress of 82 MPa. Use the maximum-shear-stress theory of failure.
Two forces, each of magnitude P, are applied to the wrench. The diameter of the steel shaft AB is 30mm. Determine the largest allowable value of P if the shear stress in the shaft is not to exceed 120MPa and it's angle of twist is limited to 7deg. Use G=83GPa for steel.
-Draw and label the diagram correctly, No diagram in the solution will be marked wrong. -Shortcut solution will be marked wrong.
. The shaft is supported by a smooth thrust bearing at A and a smooth journal bearing at B . If P = 5 kN and the shaft is made from steel having an allowable normal stress of sallow = 150 MPa and an allowable shear stress of tallow = 85 MPa, determine the required minimum wall thickness t of the shaft to the nearest millimeter to safely support the load.
