11. Design a bushed-pin type flexible coupling for connecting a motor shaft to a pump shaft for the
following service conditions:
Power to be transmitted = 40 kW; speed of the motor shaft= 1000 r.p.m. ; diameter of the motor shaft
= 50 mm ; diameter of the pump shaft = 45 mm.
The bearing pressure in the rubber bush and allowable stress in the pins are to be limited to
0.45 N/mm2 and 25 MPa respectively.
[Ans. d, = 20 mm; n 6; d, = 40 mm; 1 152 mm]

Question 41. Two 10-mm-thick by 60-mm wide hot rolled SAE 1050 steel plates are to be butt-welded together with a CJP weld. Choose an appropriate electrode for tensile loading of the joint.
2. Find the torque that a 2-surface dry disk clutch can transmit if the outside and inside lining diameters are 120 mm and 70 mm, respectively, and the applied force is 10 kN. Assume uniform wear and μ = 0.4.
4. A solid shaft was made of alloy steel, it was welded to a flat plate by a
specific size of fillet weld. If a torque is applied to the shaft, calculate the size of
the weld joint.
