Calculate the reactive force and reactive muscle moment at the knee for a seated leg , extension, with a weight of 35, 45, and 55 lbs. Assume that the leg is held at an angle?
Verified Expert
The assignment is about finding reactionary forces and moments. It is done in MS word. A 12 in, times roman font is being used.
you may do it for 0 angle. Assumptions I already made as per my understanding. force in terms of theta i could not fathom out as angles are already given.
For no 1 : Calculate the reactive force and reactive muscle moment at the knee for a seated leg extension with a weight of 35,45,and 55 lbs. assume that the leg is held at an angle theta , assume that the load is applied in a way that is remains perpendicular to the lower leg . ( i think he means here there are another weight + the leg weight ) please advise me . a.state all of your assumptions b.calculate the force and reactive muscle moments in terms of theta. c. solve for the force and reactive moments for a 35 lb load at theta = 90,60,30,0.
