Frames and Machines/ Distributed Force
Part I: Structural Analysis Frames and Machines
Problem 1
Determine the horizontal and vertical components of force at pins A, B, and C, and the reactions at the fixed support D of the three-member frame.
(Ans. FAC = 8.33 kN)
Problem 2
Determine the force P needed to support the 20-kg mass using the Spanish Burton rig. Also, what are the reactions at the supporting hooks A, B, and C?
(Ans. RA = 43.6 N)
Problem 3
Determine the force exerted on the small-diameter bar (AC). (Ans. FAC = 8.52 kN)
Problem 4
The loader carries the load shown. The bucket’s motion is controlled by two identical mechanisms (only one is shown) that together support the load. Determine:
- The force in cylinder CD
- The force in cylinder FH
Problem 5
Replace the loading with an equivalent resultant force, and specify its location on the beam measured from point B.
Problem 6
Determine the support reactions on the beam.
Problem 7
Determine the location of center of mass in the following steel plate.
Problem 8
For the machine element shown, locate the z coordinate of the center of gravity.
