The 760-N man sits in the center of the boat in, which has a uniform width and a weight per meter of 45 N/m. Determine the maximum bending moment exerted on the boat. Assume that the water exerts a uniform distributed load upward on the bottom of the boat. Express your answer to three significant figures and include the appropriate units. M_max =

Solution

the man is sitting in the center,so there wont be any bending moment,left or right to the man,because the centre of gravity of the boat in the center,and thats where he is sitting.
