Through this arrangement, a small weight can balance a massive object. If a 3kg counterweight S is used to balance a 120kg load L, what is the value of 'x'? Draw all pertinent FBDs. Use g=9.806 m/s2.

Measuring from the pivot, in the space below draw the torque-pic for the weight force exerted on the bar. Be sure your torque-pic includes both an expression for r in terms of L and also the value for the angle between r and weight force. Bar 350 Length = LFrames & 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 ABA series of compound levers is used as weighbridge.

- STATIC I need the answer within 1 hour. Thanks Using the knot method, find the force that each element in the truss system carries. Indicate whether these elements are under tensile force or under compression force. F1(N)=11 , F2(N)=23The figure on the left, below, shows a non-uniform bent rod with a mass of 5 kg. Your job is to determine the location of the center of gravity of this rod. You design an experiment: you connect a pin and cable to the rod such that it safely stays in static equilibrium under a force P that you apply. Then, you apply forces between 0-100 N, and measure the tension force on the cable using a cable tension meter. The results of your experiment are shown in the figure, on the right. Using this experiment, calculate (approximately) the horizontal distance (x in the figure) between point A and the center of gravity G of the bent rod.
