Question: Analyse the efficiency of transmitting power using a solid shaft of diameter "d" compared to a hollow shaft of diameters "Do" and "Di". The ratio "r" = Do/Di should be varied from 1.5, 1.6, 1.7, 1.8; 1.9; and 2.0 but the weight of the hollow shaft must be equal to the weight of the solid shaft. Assume the length of the shaft between the two bearings (see figure below) to be the same. must be until you find the...

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...

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...
