A 1000 kg elevator car carries a maximum load of 800 kg. A constant frictional force of 4000 N retards its motion upward, as shown un the figure below. What minimum power, in kilowatts and in horsepower, must the motor deliver to lift the fully loaded elevator car at a constant speed of 3.00 m/s? Motor

A flat plate of area 2.5 x106 mm² is pulled with a speed of 0.6m/s relative to another plate located at a distance 0.15 mm from it. Find the force and power required to maintain this speed, if the fluid separating them is having viscosity as 0.2 Ns/m².

QUESTION 1. The diameter of a pulley that is connected to the mid-span of a hollow shaft is 175mm. The pulley on the shaft is driven by a reciprocating compressor through a belt drive system, the ratio of the diameters of the connected pulleys on either sides is given as 1:2. The power transmitted by the hollow shaft is given as 45 kW while rotating at a speed of 350 rpm. The shaft has a span of 750mm which is supported on its ends by sturdy bearings that will not allow for self alignment and thereby generating bending moment at the supporting components. The tension ratio between the tight and slack sides of the belt is given as 1.9:1 with an angle of wrap of 180 degrees. Design the shaft considering that the available shaft material is BS970:070M55 that will fail in shear as per von Mises criteria, a factor of safety of 3.5 can be assumed for the material on its ultimate strength.

The propellers of a ship are connected to an A-36 steel shaft that is 60 m long and has an outer diameter of 340 mm and inner diameter of 260 mm. If the power output is 6 MW when the shaft rotates at 26 rad/sec. Determine the angle of twist in the shaft radian. G = 75 GPa. Note round off your answer in three decimal places
