Arelaxed biceps muscle requires a force of 25.0 n for an elongation of 3.0 cm; the same muscle under maximum tension requires a force of 500 n for the same elongation. the muscle is assumed to be a uniform cylinder with length 0.200 m and cross-sectional area 50.0cm^2.

Explanation:

Complete statement of the question is

A relaxed biceps muscle requires a force of 25.0 N for an elongation of 3.0 cm; the same muscle under maximum tension requires a force of 500 N for the same elongation. Find Young's modulus (Pa) for the muscle tissue under each of these conditions .The muscle is assumed to be a uniform cylinder with length 0.200 m and cross-sectional area 50.0 cm^2.

For relaxed muscle :

= force required = 25 N

= Normal length = 0.2 m = 20 cm

= elongation in length = 3 cm

= Area of cross-section = 50 cm² = 50 x 10⁻⁴ m²

= Young's modulus for the muscle

Young's modulus is given as

Under maximum tension :

= force required = 500 N

= Normal length = 0.2 m = 20 cm

= elongation in length = 3 cm

= Area of cross-section = 50 cm² = 50 x 10⁻⁴ m²

= Young's modulus for the muscle

Young's modulus is given as
