The power unit \( A \) of the tractor-scraper has a mass of 4.9 Mg with mass center at \( G_{1} \). The fully loaded trailer-scraper unit \( B \) has a mass of 23.4 Mg with mass center at \( G_{2} \). 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: \[ \begin{array}{ll} F=i & \mathrm{kN} \\ H=\text { i } & \mathrm{kN} \end{array} \]
