A square-shaped thin block of ice is floating in a lake. If a load of mass M is carefully placed at the center of the block, as shown in Fig. 1, the top surface of the ice barely stays above the water. What is the maximum load m that can be placed near the midpoint of an edge of the block, as shown in Fig. 2, so that the load would remain above the water? Assume that the load doesn’t slip off the block.
The densities of ice and water are 900 kg/m3 and 1000 kg/m3, respectively.
