Frames & Machines The truck shown is used to deliver food to aircraft. The elevated unit weighs 2000 Ib with center of gravity at G. 1- Derive the expression for the force in the hydraulic cylinder AB as a function of 0 (the angle that member FD makes with the horizontal). 2- Plot the force over the range 0° < 0 < 45° and discuss your observations. Note: | would suggest that you first solve the problem based on the position (angle) shown. You will need to determine the length of members FD and FB before solving the problem for arbitrary 0. Note that the location of the roller at D and hence the force reactions will change as 0 varies. 40" 17" 57" C 54" E 54" H AB
