Torque can be calculated by multiplying the force (N) applied at 90° to the lever arm at a distance (m) from the pivot point (point of rotation)

Torque can be calculated by multiplying the force (N) applied at 90° to the lever arm at a distance (m) from the pivot point (point of rotation), the compound SI unit for the torque is N⋅m. If the force (at 90° to the lever arm) applied is 15 N and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

\,

The magnitude of torque is given by the equation,

\,

\tau =Fd \sin \theta

\,

inserting the data given,

\,

\tau =(15N)(2m)( \sin 90^{\circ} )

\,

or

\,

{\color{Blue} \tau =30 \, N \cdot m}

A torque of 36.2 N · m is applied to an initially motionless wheel which rotates around a fixed axis. This torque is the result of a directed force combined with a friction force. As a result of the applied torque the angular speed of the wheel increases from 0 to 10.1 rad/s. After 6.20 s the directed force is removed, and the wheel comes to rest 59.4 s later. From the time the directed force is initially applied, how...

why the longer the distance a force is applied from the fulcrum the greater the output force. I want to know how this works exactly and how does a larger distance affects the amount if work done by the force. does it has to do with the input force traveling longer vertically some how creating a greater output? So far I've just gotten very general information I hope you can help me to understand this more deeply thank you.
