How To Determine Newton Meter Force

AI Thread Summary
To determine the Newton meter force requirement and RPM for an electrical motor, first calculate the RPM by dividing the distance the mass must travel by the shaft's circumference. The torque can be calculated using the formula: torque equals the radius of the shaft multiplied by the force needed to lift the weight. For a 2-inch diameter shaft lifting 10 pounds over 7 feet in 6 seconds, these calculations will provide the necessary motor specifications. Additional clarification on specific requirements may be needed for a complete analysis. Understanding these formulas is crucial for accurate motor selection and application performance.

Hello!

How do you calculate or determine Newton meter force requirement and rpm's for an electrical motor in the following example:

A device that utilizes a shaft that is 2 inches in diameter and 6 feet length. It needs to be able to lift 10 pounds and distance of 7 feet in 6 seconds. I need to know the formulas to make these calculations and the requirements needed for this application?

Thanks in advance for any assistance!

Mr. Nice Guy.

RPM can be found by dividing the distance the mass must travel by the circumference of the shaft. The torque will be equal to the radius of the shaft times the force to lift the weight. I am unsure what you are asking for in the second part of your request.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
