Design a muff coupling to connect two shafts transmitting 40 kW at 120 r.p.m. The permissible shear
and crushing stress for the shaft and key material (mild steel) are 30 MPa and 80 MPa respectively.
The material of muff is cast iron with permissible shear stress of 15 MPa. Assume that the maximum
torque transmitted is 25 per cent greater than the mean torque.

A sleeve coupling is used to connect two 50 mm shafts whose safe shearing stress is 70 MPa. Design the sleeve when it is made of cast iron with an ultimate shearing stress of 140 MPa. Also determine the factor of safety for which the sleeve has been designed. The length of the key is half the length of sleeve and the section of the key is 12.5 mm x 12.5 mm, find the shearing and crushing stresses induced in...

Two loads connected in parallel draw a total of 4 kW at 0.68pf lagging from a 120-v ms, 60-Hz line.

Two loads connected in parallel draw a total of 4 kW at 0.68pf lagging from a 120-v ms, 60-Hz line. One load absorbs 3.3 kVAR at a 0.6 pf lagging. Determine: a) The pf of the second loadb) The capacitor value in Farads required to correct the overall pf from 0.68 to 0.9 lagging for combine loads. c) The current drawn from the supply under the new power factor of 09.
