A student with a mass of 80.0 kg runs up three flights of stairs in 12.0 sec. The student has gone a vertical distance of 8.0 m. Determine the amount of work done by the student to elevate his body to this height. Assume that his speed is constant. A crane lifts a load of 1000kg very slowly through a vertical … The work done against gravity is 15 kJ. Explanation: Given that, Mass of the load, m = 1000 kg. Vertical distance covered by a crane, h = 150 cm = 1.5 m. To find, The work done against gravity. Solution, When a crane covers some vertical distance it will posses a gravitational potential energy. It is given by : g is the acceleration due to gravity

A crane can lift 5,000 kg of mass to the height of 10 m in 10 … Jul 02, 2018 · Power = Work/Time In this case the work is equal to the change in gravitational potential energy, mgh. W = mgh = (5000 kg)(9.8m/s^2)(10m) = 490000 J The time is 10 seconds, so Power = W/T = 490000J / 10s = 49000 J/s = 49000 W = 49 kW Load Charts for Cranes, Aerial Lifts, and Telehandlers Make Model Capacity Max. Fork Height Max. Boom Height Load Center Wheelbase Total Weight Load Chart; Hoist Liftruck: FR 25/35: 35,000 lbs. 95" 264" 24" 76"-112" How to calculate the electric power required to lift 100 kg … Apr 02, 2015 · At what rate do you want to lift these 100 kg? Slower the rate, lesser would be the wattage rating. Let's do a quick calculation here: power = work/time work = force x distance So power = force x distance/time or equivalently, power = force x spee… Crane Operating Near Electric Power Crane Crane in transit, no boom and load lowered as in Crane in Transit With No Boom and Load Lowered. Required Notification Before Work. A minimum of 48 hours before commencement of operations near electric power lines, notify the electrical utility for an onsite meeting to establish conditions to safely complete the operations. A crane lifts a 425 kg steel beam vertically upward a … Nov 28, 2010 · A crane lifts a 425 kg steel beam vertically upward a distance of 78 m. How much work does the crane do on the beam if the beam accelerates upward at 1.8 m/s^2? Neglect Frictional forces.

Science. you draw a 100kg sack of maize meal across the floor of a warehouse for the distance of 10m. The work-energy theorem states that the work done on an … The work-energy theorem states that the work done on an object is equal to the change in kinetic energy of that object Author: Laura Menzella Created Date: Work and Energy Review – with Answers #2 The amount of work done by a force to displace an object is found from the equation. W = F*d*cos(Theta) The force required to raise the car at constant speed is equivalent to the weight (m*g) of the car. Since the 2400-kg car weighs 2X as much as the 1200-kg car, it would require twice as much work to lift it the same distance. NAME………………………………………………………………ADM NO……CLASS..… 9.
