The block can be tipped at a maximum angle of 27.6 degrees before it falls over. To determine this, we can use the concept of the center of gravity and the tipping point of an object. When an object is tipped, the line of action of the weight force (through the center of gravity) must remain within the base of support for the object to remain stable. In this case, the base of support is the bottom end of the block, which has a width of 1.83 m. The center of gravity is located 1.12 m above the midpoint of the base. Using some trigonometry, we can determine how far the line of action of the weight force can be tilted before it goes outside the base of support: tan(theta) = h_cg / (w_b / 2) theta = atan(h_cg / (w_b / 2)) theta = atan(1.12 / (1.83 / 2)) theta = 27.6 degrees Therefore, the block can be tipped at a maximum angle of 27.6 degrees before the line of action of the weight force goes outside the base of support and the block falls over.
