Can someone check these

The power unit A of the tractor-scraper has a mass of 5.4 Mg with mass center at G1. The fully loaded trailer-scraper unit B has a mass of 24.7 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. PG, F= 1450 1450 11601450480 Dimensions in millimeters H= Determine the force P exerted on the twig G. Note that there is a horizontal line of symmetry for the handles, but there is no line of symmetry for the jaws. 21 N P= 9 mm 12 mm LET 33 25 23 mm mmmm -72 mm B Determine the force in member BE of the loaded truss. The force is positive if in tension, negative if in compression. 12 16 12 BE= 54 54 5 0 Calculate the forces in members AB, BH, and BG. Members BF and CG are cables which can support tension only. Forces are positive if in tension, negative if in compression. 4 KN 8 KN 4 m B 4m 4 m AB= 57 57 BH= Answers: RG
