climbers attempting to cross a stream place a 345 kg log against a vertical frictionless ice on the opposite side the log log is inclined at 27 degree and its center of gravity is one third of the way along its 6.3 m length if the coffecient of friction between the left end of the log and the ground is 0.86 what is the maximum mass for a climber and pack to cross without the log slipping?
