can anyone draw a diagram for this problem:

a single threaded jackscrew has a pitch of 0.5 in and a mean radius of 1.75in. the coefficient of static friction is 0.15 and of kinetic friction 0.10. (A) determine the force P applied at the end of a lever 2ft long which will start lifting a weigh of 2tons (b) what value of P will keep the jackscrew turning?

thanks i need it now. can anyone help me explain the answers thanks again.
