Question On Effects of Changing Criteria Of Pulleys

  1. Nov 5, 2014 #1
    1.What would be the effect of the following factor on the maximum power that can be transmitted. (give reasons for your answers)
    Increasing the included angle of the pulley groove.

    2. What would be the effect on the following if the load torque is increased and the speed maintains constant?
    The tension in the tight side of the belt
    The tension in the slack side of the belt
    The power transmitted

    I can plug different parts into equations and have gathered that increasing the torque will make both sides of the belt tighter and increase the maximum power transmitted however I can't explain this?

    Hi Joe, welcome to PF :)

    Please read back your post and put yourself in a helper's position: there's nothing to indicate what this is all about.
    Pick up the template once more and try to compose a self-sufficient problem formulation, ... etcetera.
    I'll be glad to help out, but give use a chance ! We're not telepathy masters, just simple scientists!

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    Basically there is a motor driving a pulley linked to another pulley via a v belt. And then that is just asking in theory what effect each has on those parts, there are no formulas to work out it is the actual reasoning behind it of which I don't understand.
    They are all self standing questions of which that is all that is given, it's asking for a written answer in theory.
