Question
Patient hoists are often used to help in moving patients around who have limited mobility. A sling
at point G is used to support a patient with a weight 640 N. A technician uses the lever to adjust
the hydraulic system located from H to F such that the member GE is horizontal. The wheels A
and C must be locked while lifting the patient, so they act as pins. Joints A, B, C, D, E, and F all
act as pins.
Using the information provided determine the following:
i. Determine if there are any two-force members (4pts)
ii. Draw the FBD for all members. (10 pts)
iii. Determine the forces acting in pins C, D, E, F. (1 Dpts)
Hint: You only need use 2 FBDs to solve for these forces.
