Question

2. [1pt] A crane of mass M has a wheelbase, E, and its centre of mass midway between the wheels (the mass of the boom is negligible). The boom has length L and makes an angle 0 with the horizontal. The crane is in contact with the ground only at its front and rear tires. The diagram shows the crane, supporting a mass m in front. We will be considering two aspects: (a) the force of the rear wheels on the ground, and (b) when the crane tips over, as a function of m and θ. Answer True or False to each of the statements below; e.g., if the first statement is true and the rest, false, enter TFFFF. You only have 5 tries! i. As shown, the crane would never tip, regardless of the size of m ii. As shown, the weight of the crane leads to a clockwise torque about the front axle iii. As shown, the force of the front wheel on the ground is equal to Mg/2 iv. For all 0<90, the crane will tip if m is large enough V. The crane is in static equilibrium. It is most convenient to calculate torques about the rear axle. Answer: Submit All Answers Last Answer: TTFFF Incorrect, tries 1/5.
