Find the period of the leg of a man who is 1.83 m in height with a mass of 67 kg. The moment of inertia of a cylinder rotating a
Lady bird [3.3K]

Answer:

1.54 s

Explanation:

Considering that the legs constitute 16% of the total weight of the man then mass, m= \frac {16}{100}\times 67=10.72 Kg

The legs also constitute 48% of his height hence H=\frac {48}{100}\times 1.83=0.8784 m

The moment of inertia of a cylinder rotating about a perpendicular axis at one end is \frac {ml^{2}}{3} hence I=\frac {10.72\times 0.8784^{2}}{3}=2.757135974Kg.m^{2}

We also know that the period is given by 2\pi \sqrt{\frac {I}{mgh}}

Here, h=0.5H= 0.5*0.8784=0.4392 m

Taking g as 9.81 kg/m2 then

T= 2\pi \sqrt{\frac {2.757135974}{10.72\times 9.81\times 0.4392}}\\=1.535132615 s\\\boxed{\approx 1.54 s}
