This is the deal, I have two pulleys with a radii of 10.0in. and 6.00in., and their centers are 40.0 in. apart. If the pulley belt is uncrossed, what must be the length of the belt? Can somebody pull me to the side and please explain this to me, I also have a couple questions about this.

    ok maybe bad example So in this you have two circles, you need to know the equation for the circumference of the circle which is 2pir^2 and use only half because the belt covers only half the circles then add the middle which is 40 but times by two because there's two lengths of it

    before you go any farther, that site you gave to my is great. I've got the belt length needs to be 81.57inches. Did I do it right?

    so you use the diameters which are twice the radii so 20 and 12 add them, then multiply by 1.6, then add 40 twice

    Oh ok your equation should be like (2radii+2radii)*1/2pi+2length

    yup, you are using half the circumference and then adding the length between the two pullys

    half the circumference of each pully, so it be 32radii?

    yea then times 1/2pi and add 80 gives you 131.2
