Yes I know I'm sorry, I would love to use it and I see it's good but I don't remember if I have to based on the forum rules.erobz said:
Well, your job is to make it as easy for you to receive free homework help here, by making it easy for helpers to interpret and quote your workings. Do think we like wasting time repeatedly asking you this simple courtesy, instead of getting down to the "helping"?Mohmmad Maaitah said:
You're right, I will do that next time for sure.erobz said:
Ever hear the expression "There is no time like the present"? You could have already been finished and on your merry way by now. Instead, you are going to wait for someone that isn't trying to prove a point.Mohmmad Maaitah said:
Yes it is. We sometime cut some slack for folks new to PF to give them time to learn it, but especially for simple equations it is very easy to use:Mohmmad Maaitah said:

The drawing is misleading.Mohmmad Maaitah said:
It's the way the horizontal dashed line has been drawn. In principle , where exactly it is drawn does not matter because it is only there to show the angle to the horizontal (37°), but it gives the impression of having been drawn from the point of contact, which it is not. Imagine it moved up a little.Mohmmad Maaitah said:
Nicely and professionally drawn but it doesn't show ##F_4##.Lnewqban said:
Net torque is the sum of all individual torques acting on an object. It determines the overall rotational effect on the object, taking into account both the magnitude and direction of each applied force.
The torque (τ) produced by a single force (F) on a cylinder is calculated using the formula τ = r × F × sin(θ), where r is the distance from the axis of rotation to the point of force application, F is the magnitude of the force, and θ is the angle between the force vector and the lever arm.
The direction of the torque is determined by the right-hand rule: if you point the thumb of your right hand in the direction of the axis of rotation, the direction your fingers curl is the direction of the torque. Clockwise torques are usually considered negative, and counterclockwise torques are considered positive.
The net torque is the vector sum of all individual torques produced by each force. This involves calculating the torque from each force separately and then adding them together, taking into account their directions (signs).
The position of the applied forces affects the net torque because torque depends on the lever arm distance (r) from the axis of rotation. Forces applied further from the axis produce greater torque, while those closer produce less. The angle of application also influences the effective component of the force contributing to the torque.
