How do you calculate output torque needed to lift a weight. Close • Posted by 1 hour ago. How do you calculate output torque needed to lift a weight. I need to lift a 16lbs weight with a 2" spool diameter spool of cable. I think that the calculation for load torque is F*spool diameter, so it would just be 16in-lbs of output torque, right?
You will need to do the mechanical leverage calculation along with the torque of the motor to determine the actual weight it will lift. The calculation will need to consider the type and pitch of the screw and it …
Stall Torque = 20 Kg/cm. The unit is Kg*cm. And when a wheel of 4" diameter, i.e. 2"=5cm radius is directly mounted to the shaft, the "force" is 20Kg*cm / 5cm = 4kg. This means: If you put a string around the wheel and use it as winch, it could lift a weight of almost 4kg (8.8lbs) before it …
May 02, 2019· https://engineers.academy/This video describes the operation of a lead screw lifting machine and explains how efficiency and lifting torque …
Let us calculate the work done in lifting an object of mass m through a height h. If the object is lifted straight up at constant speed, then the force needed to lift it is equal to its weight mg. The work done on the mass is then W = Fd = mgh. We define this to be the gravitational potential energy …
Weight Lifting Calculator. The simplest system that provides a mechanical advantage is the lever (Fig 1)Give me a lever long enough, a fulcrum and a place to stand and I shall move the earth⁽¹⁾. but …
Example - Power needed to lift a Mass. A mass of 1000 kg is lifted 10 m in 10 seconds. The work done can be calculated as. W = (1000 kg) (9.81 m/s 2) (10 m) = 98100 J (Nm) The power required is work done per unit time. P = (98100 J) / (10 s) = 9810 W (J/s) = 9.8 kW. Example - …
Lifting Motor Torque Calculations To calculate the torque required to operate a gate or lifting mechanism, the centroid (or center of mass) and weight of each component must be accounted for. The following example presents one method of computing this torque. Example lifting arm design criteria: 80/20 length (L 80/20): 10 in
Processing... : ().().: :
This tool will calculate the torque generated around an axis by a force applied at right angle to a lever arm of a specified length. Once you have selected the value and units for force and length, two conversion scales will be produced to show a range of torque values calculated for different values of force and length while the other ...
note that kg is the SI units for mass - more about mass and weight (force); Example - Improvised Car Lift. An improvised car lift can be made with a piece of lumber as illustrated in the figure above. With distance load to fulcrum 0.2 m, distance effort force to fulcrum 2 m and a load on the lever - half the weight …
Apr 18, 2019· Calculate the force required for an 8 pound wagon to accelerate at 7 m/s 2. First, convert all your units to SI. One pound is equal to .453 kg, so you'll need to multiply that value by your 8 …
Second, the power required is the speed times the torque. In a ideal system with no friction, the torque to maintain 10 m/s and 1000 m/s is the same, but the power required to produce that torque at the higher speed is 100 times more. If you needed 15 W at 10 m/s, then you'll need 1.5 kW at 1000 m/s. $endgroup$ – Olin Lathrop Apr 19 '16 at 21:46
