KIN 3112 Homework #3 Perform a dynamic analysis for a knee extension movement. The knee extensors insert on the tibia at an angle 0-30° and at a distance d-5.2 cm from the axis of rotation of the knee. The combined weight of lower leg and foot is F 48 N and its center of mass is r 0.27 m away from the knee joint axis. The joint angle with respect to the left horizontal is A-70 (Note: this is not...
A person is doing leg flexion/extension exercises from a sitting
position in order to strengthen the person's quadracept muscles.
The forces acting in the lower leg are illustrated in the figures
below.
W0 is the weight of the boot, W1 = 160 N
is the weight of the person's lower leg, FM is the
magnitude of the force exerted by the quadricepts muscle on the
tibia (shinbone) through the patellar tendon, and FJ is
the force due to the tibiofemoral...
1) In the figure below, assume the pipe diameter is 4-inches,
(f = 0.035), Distance from BC is 18-feet, distance DE is
187-feet and ∆ z = 69-feet. The elevation of C is
14-feet above the lower water surface. If the pressure
head @ C is to be no less than (–) 20 feet, what is the maximum
flow rate that can be pumped? (Flow rate in GPM)
2) If the pump from the previous problem has 63%
efficiency, what horsepower must be...

Hi! I’m wondering if anyone can help with these physics
problems from my exam krackers book? I am studying for the mcat and
the explanations in the book and student doctor are not helping me.
Thanks so much!!
