How much power is required to lift up?
Lifting Weights:
On earth it takes about 10 Newton-meters (N-m) of energy to raise a 1 kilogram mass to a height of 1 meter. Since 1 N-m equals 1 Joule, that’s 10 Joules. If it takes 1 second to lift the weight 1 meter, than you have converted 10 Joules of energy to potential energy in one second.
How much weight can a 1/2 hp motor lift?

How much horsepower does an elephant have?
One estimate I have seen is that an elephant can pull up to 9 tons = 18000 lb. However, to calculate horsepower, the speed of pulling has to be factored in. Let us postulate that the elephant can pull 18000 lb, against a coefficient of friction of 0.5, at a rate of 5 feet/second. so 18000 x 0.5 x 5 / 550 = 81.8 HP .

How much horsepower does a cold air intake add?
That’s why a cold air intake is a small investment with a rather big payoff. It makes such a big difference, in fact, that the simple process of redirecting the filter to draw cooler air is good for a horsepower gain of about 5 to 20 ponies in most cars.
What breed of horse is horsepower based on?
Originally Answered: What breed of horse was used to set the standard for horse power? The man who coined the term horsepower was James Watt. James lived in Scotland, and was trying to measure the amount of work the coal mine ponies could do. At the time, those mines were worked by Welsh Ponies .
What is torque vs horsepower?
Torque, simply, is the ability of a vehicle to perform work — specifically, the twisting force applied by the crankshaft. Horsepower is how rapidly the vehicle can perform that work . For instance, a lightweight sports car that operates at high rpm may have high horsepower, but low torque.
Is lb and lbf the same?
“Lbf” refers to the gravitational force placed by a matter on the Earth’s surface, while “lb” deals with the measurement of force. A pound force equals the product of 1 pound and the gravitational field. “Lb” and “lbf” are basically similar with each other since they both involve the same force .
How fast is 1hp?
One imperial horsepower is equal to 550 foot-pounds of force per second . MPH is a unit for measuring speed.
What is considered good torque in a car?
Both horsepower and torque are measured to give shoppers a sense of the performance they might expect from their vehicle. Engines in mainstream cars and trucks typically generate 100 to 400 lb. -ft of torque .
How fast can you go with 1 horsepower?
A 1-horsepower engine couldn’t maintain more than 20 or 30 mph in a normal car, and you could never turn on the headlights or the air conditioning. The other problem is acceleration. The bigger the engine, the faster you can accelerate from zero to 60mph.
How fast can a 300 horsepower car go?
It has a small engine that can move a curb weight of 2300 lbs to a top speed of 140 mph .
What is the load capacity?
Load capacity is the maximum allowable force that can be applied to a stage in a specified direction while meeting stage specifications . ... The amount of acceleration a stage can impart to a mass is limited to the accelerating force it can produce without exceeding a load capacity.
How do you calculate load?
Calculating an Electrical Load in a Simple Circuit
Let Power = Voltage * Current (P=VI) . Let Current = Voltage/Resistance (I=V/R). Apply Kirchoff’s Second Law, that the sum of the voltages around a circuit is zero. Conclude that the load voltage around the simple circuit must be 9 volts.

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).
How much weight can a garage door opener lift without springs?
For an automatic garage door, the lift of the weight is subject to the horsepower of the garage door opener. A half of horsepower can lift roughly around 300 pounds.
