A rectangular block (Object B) is on the ground where the coefficient of friction between the block and the ground is 0.25. The weight of the block is at the centre of the block. There is a triangular distributed load acting against one of the vertical faces (left side as shown in the diagram) of the block. Gravitational acceleration g = 9.81m/s2. (a) If the height of the triangular load is 60m, can the block slide or overturn? (b) What is the maximum value of Z to ensure that the block does not overturn or slide? (c) Comment on the possible structure representing this setup
