Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.

Question

3. An 8-m steel shaft rotating at 180 rpm has 70kW applied at a gear that is
3.0m from the left end where another 60kW are applied. The shaft in
between the two gears is solid with diameter=40mm. At the right end,
80kW are removed and another 50kW leaves the shaft at 3.60m from the
right end. The shaft is hollow between these gears with outside
diameter=80mm and inside diameter=70mm. The shaft between the 7OKW
and 50kW is hollow with outside diameter=60mm and inside
diameter=50mm (a) Find the stresses in each shaft. (b) Determine the
angle (in radians) by which one end of the shaft lags behind the other
end. Use G=83GPa.

Problem 3
Problem : A train of spur gears with 20°full-depth involute teeth is shown in the Figure below. Gear 1 is the driving gear and transmits 50 kW power at 300 rpm to the gear train. The number of teeth on gears 1, 2, 3 and 4 are 30, 60, 25 and 50 respectively, while the module for all gears is 8 mm. Gears 2 and 3 are mounted on the same shaft. Gear 1 is rotating in the clockwise direction when seen from the left side of the page. The shaft is made of plain carbon steel 40C8 (Syt = 380 N/mm2) and the factor of safety is 2.

Hi, I need help with this question.
A motor is used to drive a gear assembly at 200 rpm. The main gear is in the center of a 1 m long (0.5 m to the left and right of the gear) 50 mm diameter solid circular shaft, and power is taken from the two shaft ends. 25 kW is taken on the left end and an unknown amount of power is taken at the right end. the torque to the left side of the gear is? maximum shear stress to left of gear? If the maximum shear stress on the shaft to the right of the gear is 125 MPa, approximately how much power is being drawn off from the right side of the shaft? The shaft can be made from 6061-T6 aluminum. It has adequate strength to withstand the loading conditions in the scenario, including the loading on the right side of the shaft. true or false?
pls expalin to me step by step and write clearly. i will rate your answer immediately thanks
