A 3” Φ diameter short shaft carrying two pulleys close to the bearings transmit how much horsepower if the shaft makes 280 rpm?

The shaft is subjected to the axial force of 40 kN. Determine the average bearing stress acting on the collar C and the normal stress in the shaft. 

A shaft is subjected to a maximum torque of 14 KN-m and a maximum bending moment of 10 KN- m at 
a particular section. Determine the diameter of the shaft according to maximum shear stress theory if the 
elastic limit in simple tension is 180 MPa

In the figure shown below there are 125 ft of 2 -in pipe, 75ft of 6 -in pipe, and 150 \mathrm{ft} of 3 -in pipe, all cast iron. There are two 90 elbows and an open globe valve, all flanged. If the exit elevation is zero and the elevation at A is 100 ft, what horsepower is extracted by the turbine when the flow rate is 0.16 of water at ? For water at , take and slug/ft.s. For cast iron, . For Re=113500,37800, and 75600 , take f 0.0314,0.0266, and 0.0287 respectively.

sharp 2" entrance: K=0.5; two 2" 90 elbows: K=2(0.39)

2" sudden expansion: K 0.79 ; 3" open globe valve: K 8.5
