Help with this Mechanical Engineering Calculation

02/05/2011 1:55 PM

Hi I'm doing an assignment and I need some help. My question is, A turning moment of 6Nm is generated by a force of 24N acting at right angles to a lever. What is the effective length of the lever in meters?

The torque or turning moment acting on a body is defined as the product of the magnitude of the force and the perpendicular distance of the line of action of the force from the axis about which the body is being rotated.

You can manage the division sum....can't you?

I hope you are still in high school, hopefully first year! Mathematically, this is expressed by M = Fd, where F is the force, d is the perpendicular distance between the force and the fulcrum, and M is the turning force known as the moment or torque. (F=24N, M=6Nm) Then (d=M/F) What are you going to do if someone asks you a real problem?

torque= perpendicular distance of force vector from the point of action * force applied

using right hand thumb rule find the direction of torque also if necessary..... hope this soves ur plob
