Frames are designed to support loads and are usually stationary. Three force members explained 55. In Class Problem 1 Find the components EXAMPLE OF LINEAR PROGRAMMING A manufacturer produces two products, X and Y , with two machines, A and B. Centroids and Distributed Loads. Determine the reactions, R1 Machines contain moving parts that transmit or alter applied forces. Frame example problem #1 56. Frame Example Click to view movie (91k) Frame Solution Click to view movie (102k) Begin by isolating each segment of the frame and labeling the known and unknown forces. 58. The main strategy of tackling problems in this section is to: Separate the frame/machine into its individual members. to add a counterweight to a force in the upward direction to change the direction of force magnitudes to support loads to add a fixed point for calculations of force vectors and magnitudes Submit Request Answer Provide Feedback Next > The cost of producing each unit of X is: • for machine A: 50 minutes, • for machine B: 30 minutes. The frame is in static equilibrium. Assuming the density of water is 1000 kg/m 3, determine the weight of the combined system. Frames and Machines Example 4 Given: The frame shown is loaded with a 100kg package and is supported by pin supports at joints A and B. Determine the mass and the weight of the air contained in a room whose dimensions are 6 m*3 *6 m 8 m. Assume the density of the air is 1.16 kg/m 3. A good example is the plier. 3.
