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.  Determine  the

acceleration of the plane and the normal reactions on   the

nose wheel at A and each of the two wing wheels located at

B. Neglect the mass of the wheels and, due to low velocity, neglect any lift caused by the wings.

Prob. 17–27

*17–28. The assembly has a mass of 8 Mg and is hoisted using the boom and pulley system. If the winch at B draws in the cable with an acceleration of 2 m>s2, determine the compressive force in the hydraulic cylinder needed to support the boom.The boom has a mass of 2 Mg and mass center at G.
