I was thinking the for I was calculating was the tension force on the rope.

f = force Is that not correct?

Thank you very much voko for all your help :)

Thanks for your reply voko. I can explain how I got the acceleration equation. Is the equation correct? Assuming the acceleration equation to be correct. To calculate the torque: Torque(T) = Inertia x Angular Acceleration and... Angular Acceleration = a/r = 7.84/0.5 = 15.68 m/s T = 0.625 x...

Thanks for your reply haruspex So f = ma f = 10 x 7.84 f = 78.4N So the Torque on the pulley shaft - T = fr T = 78.4N x 0.5m T = 39.2Nm Is this correct? Thanks.

Thanks for your reply voko. ok, so I have followed the above advise. Would you please check my following calculations so I can be sure I understand correctly. To calculate angular acceleration 1st calculate pulley inertia: pulley inertia(I) = 1/2mr2 (2 represents squared) I = 1/2 x 5 x 0.25 I...

To calculate acceleration 1st calculate pulley inertia: pulley inertia(I) = 1/2mr2 (2 represents squared) I = 1/2 x 5 x 0.25 I = 0.625 acceleration(a) = hanging mass weight divided by mass of hanging mass plus pulleys inertia divided by radius squared. a = 98 / (10 + (0.625 / 0.25)) a = 98 /...

The tension in the rope is mass x gravity = 10 x 9.8 = 98N So my answer should be: Torque = Force x Radius Torque = (10kg x 9.8) x 0.5m Torque on pulleys shaft is = 49Nm Is this correct? Thanks

Hi Here is my question: A solid disc pulley with a 5kg mass, radius of 0.5m has one layer of thin rope coiled around it. On the other end of the rope is a metal block with a mass of 10kg. Calculate the following (without take rope friction into account. also the rope does not slip): 1. The...

Thanks Aero_UoP

Can anyone give me the link to any useful resources on the internet?

Hi I'm 40 and teaching myself physics from the internet and have the following question but don't where to start! Here is the question: A solid disc pulley with a 5kg mass, radius of 0.5m has one layer of thin rope coiled around it. On the other end of the rope is a metal block with a...
