Chapter 4, Problem 66P

At the shown position, the ground reaction forces measured using a force platform are 600N in the vertical direction (Fy) and 200N in horizontal direction (Fx). The mass of the limb below the knee is 4kg with the centre of gravity at the point G. Determine the forces and moment applied to the knee joint. Draw correct free body diagram using any part of the body shown below.

Express and identify the resultant of the two forces and one couple shown acting on the shaft angled in the x-z plane Assume F = 310 Ib, M = 500 Ib-ft, a = 7 in., b = 20 in., 0 = 27°

AAAAAAAAAAAAAAAAAAAAAAAAAAAAA

Replace the three horizontal forces and applied couple with an equivalent force–couple system at O by specifying the resultant R and couple MO. Next, determine the equation for the line of action of the stand-alone resultant force R. Equation for line of force too thanks pls handwritten

The homogeneous bars have a mass as follows: bar AC has a mass of 7 kg, bar ABhas a mass of 10 kg, and rod BD has a mass of 2 kg. In the drawn position, therod AC has an angular velocity of 4 rad/s and an angular acceleration of 2 rad/s2, both clockwise.Determine the magnitude of the moment M acting on the member AC. Give all the equations neededto solve this question without calculating it

2/92 The pedal-chainwheel unit of a bicycle is shown in the figure. The left foot of the rider exerts the 40-lb force, while the use of toe clips allows the right foot to exert the nearly upward 20-lb force. Determine the equivalent force-couple system at point O. Also, de- termine the equation of the line of action of the sys- tem resultant treated as a single force R. Treat the problem as two-dimensional. 30° 40 lb 15° 6.5" 20 lb 6.5" 5° Problem 2/92

You have to draw a complete free body-diagram in a paper sheet.

Solve these two problem with explanation.
