W=Fd

F=mg=(200kg)(9.8m/s2)=1960kgm/s2=1960N

W=(1960N)(3m)=5880Nm

How does a lever chain hoist work?

A lever chain hoist works by using a lever to lift heavy loads. As the operator pulls the lever down, it engages a ratcheting mechanism that lifts the load. The chain attached to the hoist is used to support and lower the load.


How much work does a crane do as it lifts a 240 kilogram crate from ground level to a height of 165 meters?

The work done by a crane lifting a 240 kg crate to a height of 165 meters is equal to the change in potential energy of the crate. The work done can be calculated using the formula: Work = force x distance. In this case, the force is equal to the weight of the crate (240 kg x 9.8 m/s^2) and the distance is 165 meters.


How do electric chain hoists work?

Electric chain hoists use an electric motor to power a chain mechanism that lifts and lowers heavy loads. When the motor is activated, it drives the chain to lift the load, and when the motor is reversed, the load is lowered. These hoists are commonly used in industrial settings for their efficiency and precision in handling heavy materials.


A ride at a park lifts people 30 m into the air holds them at that height and then drops them What should be the reference point if you want to study the motion of the people dropping?

The reference point for studying the motion of the people dropping should be the initial height from which they are dropped, which is 30 meters above the ground. This reference point will provide a consistent framework for analyzing their motion as they fall downward.


A bowler lifts her bowling ball a distance of 0.5 meters using 35 joules of energy. What is the mass of her bowling ball?

35 Joules is 35 newton-meters. The nergy is weight times distance = weight x .5 meters = 35 so weight is 35/.5 = 70NForce = weight =mass x acceleration ; mass =weight/gravity accel = 70/9.814 = 7.13 kg

Do you need a special van to install a wheelchair lift?

There are different types of wheelchair lifts. There are hitch mounted wheelchair lifts that utilize the hitch on a car, truck or van. They do not require any special vehicle. You have inside vehicle lifts that hoist the wheelchair or scooter into the van. The platform lifts can lift the wheelchair or scooter with someone in it. If it doesn't work with your van don't worry most of the vans can be re-fitted to install the lift.
