## How long will it take a 2.5 KW motor to lift a 80kg block 30m high?

Motor will take 9.4 s to lift block. Work done by motor to lift block is equal to change in gravitational potential energy of block.

## How do you calculate the lifting capacity of a motor?

Force needed to hold 100 kg against gravity = 100*9.8, rounding it up to 1000N. Let’s say the machine lifts it up at a rate of 1 meter per second. So power needed would be 1000 x 1 = 1kW. But this is the power needed without frictional and other losses.

## How do you calculate the power needed to lift a load?

If you lift a 2 kg weight 1 meter in 1 second, then the rate of energy conversion is 2 x 10 = 20 Joules per second, or 20 Watts of power. If you can keep lifting a 1 kg weight to a height of 1 meter every second, weight after weight after weight, then you will be steadily producing 10 Watts of power.

## How much weight a motor can lift?

The maximum torque is given as 1.2 kg*cm (which includes the gearbox-transition), which means having wheels with an radius of 1 cm (or 2cm in diameter) will give you a force that is equivalent to 1.2 kg in weight at nominal voltage, as long as your electronics can provide a current of 300 mA (load current).

## Does the power expended depend on how fast it is lifted?

No. Work is independent of time. Power is dependent on time, so lifting it faster would require more power.

## How do you calculate retarding force?

A retarding force causes the acceleration of an object to be negative. In F=ma , where F is the resultant force, the force acts against the direction of the object’s current velocity is the retarding force. Formula used: F=ma and F=ma,a=vt.

## How much weight can a 1 hp motor lift?

This means with 1 hp, you can lift about 550 lbs (250 kg) at a rate of 1 ft/sec, 1100 lbs at a rate of 0.5 ft/sec, 225 lb at a rate of 2 ft/sec, 1 lb at a rate of 550 ft/sec, and so on.

## How much weight can a 1/2 hp motor lift?

A 1/2 horsepower garage door opener can lift approximately 300 pounds, which is the average weight of a two-car steel door. A one-horsepower opener can easily lift approximately 400 pounds. The greater the horsepower, the faster the opener can lift the door, although some are designed to lift faster than others.

## How much power is expended if you lift a 60 n crate?

How much power is expended if you lift a 60 n crate 10 meters in 1 second? Answer: Answer is 600 w.

## How much force is needed to lift the 10Kg weight?

How much force is needed to lift the 10Kg weight? The correct answer is (B) 5 Kg. In a double-pulley system, the force is equal to the weight divided by two. It will require a 5 Kg force to lift a 10Kg weight.

## How much energy does it take to lift 1kg 1m?

Unit of energy is Joules (J) or Kg m^2 /s^2. Therefore the energy required to lift the object of mass 1kg to the height 1 m is 9.8 Jules.
