side force port = 135 sin 37
side force starboard = F sin 45
so
F = 135 (sin 37 / sin 45)
for no net force to either side
two crewman pull a boat through a lock, one with a force of 135N at an angle of 37 degrees relative to the forward direction of the raft. The 2nd crewman on the opposite side of the lock pulls at an angle of 45 degrees, with what force should the 2nd crewman pull so that the net force of the two crewman is in the forward direction
