    Lever Torque
AI Thread Summary
To calculate torque for a bent lever, the key factor is the perpendicular distance from the force's line of action to the pivot point. The shape of the lever does not affect the torque calculation as long as the force is applied correctly. Both diagrams yield the same torque if the force (N) and distance (x) are equivalent, but the actual values of x differ in each case. For maximum torque, the force should be applied perpendicularly to the line connecting the lever's end to the pivot. Understanding these principles clarifies the torque calculation process.

to calculate the torque (N*x) which one is correct? the one on top, or below.

I don't understand the question. The fact that the lever is bent doesn't matter. To find the torque, you want the perpendicular distance from the line of action of the force to the pivot. If N and x are the same, the torque is the same for both diagrams.
 
sorry the diagram is unclear, but the X is different for the first case, and the second case, N is the same.
 
but anyway, i think i understand it now, thanks!

I think I know what you're asking. Imagine a straight line connecting the end of the lever to the pivot. To maximize the torque for a given force, you want the force to be perpendicular to that line. (Neither diagram shows that.) That will maximize your value for X.
 
thanks for your help!
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
