Final answer:
The statement that the knee bends 30° during mid stance of gait for shock absorption is false. The knee undergoes slight flexion, not a full 30° bend, during mid stance for shock absorption and support.
Step-by-step explanation:
The statement 'During mid stance of gait, the knee will bend 30° for shock absorption' is False. Mid stance refers to the phase in the gait cycle where the body weight is fully supported by the leg in contact with the ground. Normally, the knee experiences only a slight flexion during mid stance for shock absorption, not as much as 30°. The knee is mainly extending during mid stance to provide support for the body's weight. Shock absorption in the legs, as in the case of a kangaroo hopping, is indeed achieved by bending the legs, but this does not equate to a fixed 30° bend in the human knee during mid stance of gait.
