mass The power unit A of the tractor-scraper has a mass of 5.9 Mg with mass center at G₁. The fully loaded trailer-scraper unit B has a of 22.7 Mg with mass center at G₂. Positioning of the scraper is controlled by two hydraulic cylinders EF, one on each side of the machine. Calculate the compression F in each of the cylinders and the magnitude of the force supported by each of the pins at H, one on each side. Assume that the wheels are free to turn so that there are no horizontal components of force under the wheels. Answers: F= i H= i 870 1480 1480 11701480540 Dimensions in millimeters 1 KN KN

The round stepped shaft (diameters d and D) shown below is a design for an exoplanet rover wheel axle. Assuming the wheel is stuck, a torque from the motor is transmitted to the axle but it is not rotating. The reaction of the weight of the rover on the ground and the torque the wheel applies to the ground are represented by the force F acting in the center of the wheel hub (not shown) at point C. There is a sharp fillet at B with radius r shown below. Bearings are shown at point A and next to point B. You may assume the bearing at B resists the bending moment caused by the force F and acts like a fixed reaction.
