In  a human pyramid in a circus, the entire weight of the balanced group is supported by the legs of a performero who is  lying on his back (as shown in Fig. 9.5). The combined mass of all the persons performing the act, and the tables, plaques etc. involved is 60 kg. Each thighbone (femur) of this performer has a length of 50 cm and an effective radius of 2.0 cm. Determine the amount by which each thighbone gets compressed under the extra load. img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/NCERT_PHY_V02_XI_C09_S01_003_Q01.png" width="80%"
