WebAn elevator must lift 1000 kg a distance of 100 m at a velocity of 4 m/s. What is the average power the elevator exerts during this trip? The work done by the elevator over the 100 meters is easily calculable: W = mgh = (1000)(9.8)(100) = 9.8×10 5 Joules. WebTo lift 100 kg (220 lbs) using a pressure of 1450 psi (about 100 atm), the minimum area needed to apply this force is: $$area=\frac {220\ lbs}{1450\ psi}$$ $$area=0.152\ in^2$$

Explanation: w/T=power. not direct. force=mass×acceleration. acceleration=10. so since mass =30kg. force =30×10=300. distance=10m. force×distance. 300×10 … Web50 J. A 5kg mass is lifted upward at a constant speed to a height of 10 m. Calculate the work done by the lifting force. 98 J. Calculate the work done by gravity when a 10kg mass …
WebNov 8, 2015 · Lifting the weight at a certain speed requires power from end to end, always measured in watts. At the output, the power to lift the weight is speed*force in m/s and N. Through the geartrain the power is angular speed * torque, in radians/s and Nm. At the motor, the power is volts * amps. WebBecause the difference in the up and downforce is 0.069 pounds. each cubic foot of helium could lift 0.069 pounds. In order to lift a single kilogram, you would need 1449 cubic feet of helium. Now we have to transfer the cubic feet to liters. 1 cubic foot= 28 litres 115920x28 Theoretically, it would take 3245760 liters to lift 80 kilograms.
WebJan 29, 2016 · The force required to lift an object is its weight (the force of gravity) Weight: F g = mg. I will use 10 for g, you may be using 9.8 or 9.81 in your class. F g = 30kg ⋅ 10 N kg = 300N. W = F d. W = 300N ⋅ 3 2 m. W = 450J. Answer link.
