    Finding force using moments problem

    I want a means of comparing players against each other. So i think by finding their power at certain positions using the static force and velocity at that point will do for comparing players as the force will increase if a player chooses to put a heavier weight on the machine and also it will...

    Finding force using moments problem

    Thanks, yes by static force i meant the force to balance the system at certain angles. I have a sensor on the equipment that will tell me acceleration and velocity throughout the movement. By multiplying the force mentioned above by velocity i get a power reading. This is not the true power...

    Finding force using moments problem

    Sory for being unclear. I know Fh as i have calculated this for various positions. The scenario is from a piece of gym epuipment where a person pushes a mass around a fixed pivot point. As the persn pushes they need to apply more force. I an interested in finding out what is the fh...

    Finding force using moments problem

    Hello I am having trouble understanding a concept of what force i have found and how i can maniplate this data. I have attached image of a triangular frame which has a 10Kg mass hanging from it at one point. I know how to calculate the Force Fh using moments. i am unsure what this force...

    How to calculate moments to find a force

    Im just unfamiliar with unfamiliar with these calculations but have to do them as part of a project. If i use the new free body diagram attached and the unit was to rotate about point a i assume my new moments would be calculated by: Anticlockwise moments = 1000(.65) Clockwise moments = F(.6)

    How to calculate moments to find a force

    I'm looking at a problem and am having trouble finding the force using moments. To be honest I'm not sure am i going about it the correct way. Attached is a sketch of the problem, Is the cclockwise moment about A = .5m(1000N) = 500Nm and the anti clockwise moment about A = .75m(F)...

    Force free body diagram problem on gym equipment

    Yes that makes sense. So at the start it will require very little force to start the motion from static and this will increase significantly as the angle increases?

    Force free body diagram problem on gym equipment

    Am i right in saying the following looking at the basic free body diagram? Fac = 1000/sin 15 =3863N ? Fh = Cos15 * Fac = 3732 ?

    Force free body diagram problem on gym equipment

    Cool, unfortunately I am still struggling. I have drawn a free body diagram and attempted to solve the problem but I am getting a value for Fh of over 3000N for a weight of 1000N on the machine. I have feeling I am goin wrong somewhere. When Does this seem large or strange? I have attached...

    Force free body diagram problem on gym equipment

    Thanks very much for the help. i am studying engineering but have done very little in that area. For a project I'm investigating how the force a player has to exert as he moves through the full push because the resistance is increasing. I must create an excel program that will allow the...

    Force free body diagram problem on gym equipment

    I'm looking at the force required to move the weights, i have a few sketches attached on a word document with an idea of how the apparatus works. Will the force required to lift the mass increase as the player moves forward. Any help is appreciated as i am lost with this problem at the...
