Up F-Pcos(50) F=Pcos(50) Across R+Psin(50)-15g Using what we know F=Coeficiant of friction x R so F=0.2R Now after that i have to eliminate R However after doing it I cant find the correct value for P which is 37 --------------------     | ||

 IRC Nickname: Pyroclastic0 Group: Elite Guardian Posts: 1158 Member No.: 35 Joined: December 30, 2007 Total Events Attended: 221 | I thought it would be the maximum static friction = 0.2*15*g=Psin 50 but that's 38 :s -------------------- Having a fight on the internet is alot like the participating in the special olympics you may win, but you're still retarded
