The triceps muscle in the back of the upper arm extends the forearm.
iren [92.7K]

To solve this problem it is necessary to apply the concepts related to Torque as a function of Force and distance. Basically the torque is located in the forearm and would be determined by the effective perpendicular lever arm and force, that is

\tau = F \times r

Where,

F = Force

r = Distance

Replacing,

\tau = 2*10^3*0.03

\tau = 60N\cdot m

The moment of inertia of the boxer's forearm can be calculated from the relation between torque and moment of inertia and angular acceleration

\tau = I \alpha

I = Moment of inertia

\alpha = Angular acceleration

Replacing with our values we have that

I = \frac{\tau}{\alpha}

I = \frac{60}{120}

I = 0.5kg\cdot m^2

Therefore the value of moment of inertia is 0.5kg\cdot m^2

List three unique examples of situations in your daily life where expansion and contraction occur.
Vera_Pavlovna [14]
When you put ice in the freezer, the water expands when in gets cold.
the sidewalks have cracks in them to make room for the expansion and contraction when it heats up and cools down.
as you drive a car, the heat from combustion causes metal to expand. when you turn the car off, the metal cools down and contracts

4500 miles to inches
Volgvan

Answer:

2.8512*10^8 inches

Explanation:

Seeing as the ratio for miles to inches is 1 mile = 63360 inches, set up an equation. 1 mile / 63360 inches = 4500 miles / x inches. Cross multiply and simplify to 2.8512*10^8 inches. Hope this helps! :)
