Answer 1

Answer #1

Solution : the power of the system is given by the equation as

Power = Force x velocity

Here force required in upward direction = weight of the system + friction force = 1800x9.81 + 4000 = 21658 N

Now power= 21658 x 3 = 64974 watt = 6.49 x 10⁴ watt

Use the worked example above to help you solve this problem. A 1.19 103-kg elevator car carries a maximum load of 7.40 102 kg. A constant friction force of 4.07 103 N retards its motion upward, as shown in the figure. What minimum power, in kilowatts and horsepower, must the motor deliver to lift the fully loaded elevator at a constant speed of 3.00 m/s? P = kW P = hp
