While slowly walking, a man having a total mass M places all his weight on one foot.
Question:
While slowly walking, a man having a total mass M places all his weight on one foot. Assuming that the normal force NC of the ground acts on his foot at C, determine the resultant vertical compressive force FB which the tibia T exerts on the astragalus B, and the vertical tension FA in the Achilles tendon A at the instant shown.
Units Used:
kN = 103 N
Given:
M = 80 kg
a = 15 mm
b = 5 mm
c = 20 mm
d = 100 mm
FB FA Nc
Step by Step Answer:
0 F 0 Nc Mg Nc 785 ...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
