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,...
3) MACHINE (12 points) The skid steer loader has a mass of 1.18 Mg, and in the position shown the center of mass is at G1. If there is a 300-kg stone in the bucket, with center of mass at G2, determine the reactions of each pair of wheels A and B on the ground and the force in the hydraulic cylinder CD and at the pin E. There is a similar linkage on each side of the loader. a....
The truck has a mass of 8 Mg and mass center at G1 and the trailer has a mass of 2 Mg and mass center at G2.Part A Determine the absolute maximum live bending moment developed in the bridge. Follow the sign convention. Express your answer to three significant figures and include the appropriate units.
P.1. The tractor boom supports the uniform mass of 475 kg in the bucket which has a center of mass T0.25 m at G. Determine the force in each 1.5 m 0.3 m hydraulic cylinder AB and CD and the resultant force at pins E and F. The load is supported equally on each side of the tractor by a similar mechanism. (20 points) 0.1 m 1.25 m 0.2 m 0.6 m 0.4 m 0.3 m
Hibbeler 17-26: The jet aircraft has a total mass of 22 Mg and a center of mass at G. Initially at take-off the engines provide a thrust 2T = 4 kN and T' = 1.5 kN. Neglect the mass of the wheels and, due to low velocity, neglect any lift caused by the wings. a. Find the acceleration of the plane b. Find the normal forces on the nose wheel and each of the two wing wheels located at B....
