A solid cylinder with radius 0.160 m is mounted on a frictionless, stationary axle that lies along the cylinder axis. The cylind

agasfer [191]

Answer:

we have τ = I * α as the rotational equation of motion

and we also have τ = F * r

so the torque τ = 5* 0.16 Nm = 0.8 Nm

from your plot of θ vs T^2 , calculate the slope of the line

this slope will be angular acceleration α.

Then you get I = τ/α

The magnitude of the frictional force along the plane is most nearly

Svetach [21]

Answer:

F = N*μ or F =m*g*μ

Explanation:

The friction force is defined as the product of the normal force by the corresponding friction factor.

When a body is in equilibrium over a horizontal plane its normal force value shall be equal to:

$N = m*g\\where:\\m=mass [kg]\\g=gravity [m/s^2]\\N= normal force [N]$

if we simplify this formula more for a balanced body on a horizontal plane, we will have.

$F=m*g*u$
