QUESTION 1 It is required to design a square key for fixing a gear on a shaft of 27 mm diameter. The shaft is transmitting torque of 195,844 N.mm to the gear. The width of the key is equal 7 mm. The key is made of steel 50C4 (sy - 577 N/mm2) and the factor of safety is 3. For key material, the yield strength in compression can be assumed to be equal to the yield strength in tension. Determine...

3. Power transmission is an important engineering application and relies on the integrity of the shaft designs. Assume a solid, circular steel shaft with a uniform diameter d 50 mm and a total length I3 m. At its midpoint, a belt passes over a pulley and delivers 50 kW power to the shaft. This power is used to drive two machines at either end of the shaft. Machine 1 consumes P1 20 kW and machine 2 uses P230 KW. The...
