CIVE 260 Homework 5
Frames and Machines/ Distributed Force
Part I: Structural Analysis Frames and Machines
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)
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)
Determine the force exerted on the small-diameter bar (AC). (Ans. FAC = 8.52 kN)
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
Replace the loading with an equivalent resultant force, and specify its location on the beam measured from point B.
Determine the support reactions on the beam.
Determine the location of center of mass in the following steel plate.
For the machine element shown, locate the z coordinate of the center of gravity.
