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.
