well those exams are invalid to me as i live in the uk lol.. I'm taking foundation to electrical engineering degree so like i say this has nothing to do with the course I'm studying just for own personal knowledge.. thank you for pointing out the mistake though

well the tutor of the class gave me the answer and how to solve it.. I'm not even studying mechanics. its all just additional knowledge that i asked for to broaden my knowledge. I'm studying electrical engineering. What is SAT and GRE? I'm from the uk not the states

yes I'm not disagreeing with you but as the solution i have got is correct why are you going any further with it? i know it should be Nm but its a typo

yeah i did check with the tutor who said what i had done was right

well a breaking force is a negative force.. and i added it as it needs to have xNm to accelerate the wheel but also needs an extra 2Nm force to overcome the friction

i think i'v got it now.. i took the 80N and 120N and subtracted them together to give me the net force which i then multiplied by the radius of 0.1m to give me 4Nm i then added the friction to give me 6Nm. From there i used the equation T=Ialpha and rearranged so alpha = T/I 6/400 = alpha...

Well Torque is equal to inertia multiplied by alpha and as alpha is the acceleration which i need to find out. I have pages and pages of equations and workings out ranging from using omega to mechanical advantage but it would take a long time to write it all down.. obviously as i don't know...

A flywheel is driven by a pulley system. friction in the system exerts a braking force of 2Nm. The moment of inertia is 400kgm2. The forces in the pulley belt are 120N on the tight side and 80N on the slack side. Pulley diameter is 0.2m Calculate the acceleration of the wheel. the pulley...
