Question

Chapter 4, Practice Problem 4/13 The power unit A of the tractor-scraper has a mass of 6.0 Mg with mass center at G1.The fully loaded trailer-scraper unit B has a mass of 22.9 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. 1630 1630 1160 1630 590 Dimensiona in millimeters Answers: Click if you would like to Show Work for this question: pen Show Work
