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.

Best ResponseYou've already chosen the best response.1ok 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

Best ResponseYou've already chosen the best response.0before 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?

Best ResponseYou've already chosen the best response.1so you use the diameters which are twice the radii so 20 and 12 add them, then multiply by 1.6, then add 40 twice

Best ResponseYou've already chosen the best response.0thats what i did wrong. i put the radii , not the diameter.

Best ResponseYou've already chosen the best response.1Oh ok your equation should be like (2radii+2radii)*1/2pi+2length

Best ResponseYou've already chosen the best response.0Would'nt you call that the circumference

Best ResponseYou've already chosen the best response.1yup, you are using half the circumference and then adding the length between the two pullys

Bbambino1976

Best ResponseYou've already chosen the best response.0half the circumference of each pully, so it be 32radii?

Best ResponseYou've already chosen the best response.1yea then times 1/2pi and add 80 gives you 131.2

Best ResponseYou've already chosen the best response.0thankyou so much.but I'm getting 130.27

Best ResponseYou've already chosen the best response.0I just recalculated and came up wth 131.2
