Hi everybody, I require assistance in solving this problem:
A transmission belt passes tightly around 2 pulleys and crosses itself between them. The radii of the pulleys are 3m and 2m respectively, and their centres are 13m apart. Calculate:
a) the length of the belt
b) the total area enclosed by the belt.
I would like to know the working out required for these questions.
I have also attached a simple diagram of the problem to aid in visualisation. Any assistance would be much appreciated.
