Answer:

1.4584 kgm^2

Explanation:

Time period of a physical pendulum is given by T=2Π\sqrt{\frac{I}{mgd}}

Here f=0.290 so T=\frac{1}{F}=\frac{1}{0.29}=3.44827

Mass =2.40 kg

d=0.300 m

g =9.8 msec^2

So 3.448=2\times \pi \sqrt{\frac{I}{2.4\times 9.81\times 0.300}}=1.4584  kg-m^2

So the moment of inertia of the pendulum about the pivot point will be 1.4584 kg-m^2

Answer:

See below

Explanation:

Torgue = f * distance    basically ...so if you want to increase torque with same  f   then the distance ( lever arm)  must be increased
