Figure Q3 (a) shows a solid 40 mm diameter steel shaft which is supported by smooth bearings at B and D
Figure Q3 (a) shows a solid 40 mm diameter steel shaft which is supported by smooth bearings at B and D. It is coupled to a motor at C, which delivers 6 kW of power to the shaft while it is turning at 50 Hz. The modulus of rigidity of steel is 80 GPa. The shaft is free to turn in its support bearings at B and D. If gears A and E consume powers of 2 kW and 4...

A solid steel bar of circular cross section has diameter d = 40 mm, length L = 1.3 m and shear modulus of elasticity G = 80 GPa. The bar is subjected to torques T acting at the ends. If the torques have magnitude T = 340 Nm, what is the maximum shear stress in the bar? What is the angle of twist between the ends? If the allowable shear stress is 42 MPa and the allowable angle of twist...

A hollow shaft consisting of a steel tube of 50-mm outer diameter is to transmit 250 kW of power while rotating at a frequency of 30 Hz. Determine - (7 points) (a) the tube thickness that should be used if the shearing stress is not to exceed 100 MPa. (3 points) (b) since in this simplified design calculation, the only stress considered is shear stress exerted on the shaft due to torques. Without taking into account of how power is...
