The pendulum frequency is dependent upon the length of the pendulum. The torque is the turning force of the pendulum.
A torque acting on an object tends to produce rotation.
Torque= length x force. Lenght is the distance to an object. Force must be perpendicularly acting on the object. In your question, you did not specify neither force and length of the knob. So I cannot give you a torque value. I believe the SI unit for torque is "Nm", assuming that you calculated your torque using all SI units. Then you have to convert Nm to pounds.
Just as a net force is the vector sum of all the forces acting on an object, a net torque is the vector sum of all torques acting on an object.

A screw is an inclined plane wrapped around a shaft. The inclined plane is a simple machine that offers the user a mechanical advantage. The shaft is what transmits a torque to that advantage.

There are a number of things that affect the pendulum and how it operates. Let's just start setting them down. The mass of the pendulum and its string, cable, rod, or whatever it is that it is suspended from. The length of the suspension cable or rod. The nature of the pivot point from which the suspension is tied, or, more specifically, the friction generated by the pivot. The air resistance to the pendulum and its suspension. The latitude at which it is operated (because a small amount of torque will be applied at anything more than 0o). The nature and loss of the driving mechanism for the continued movement of the pendulum. The temperature of the surrounds of the pendulum and its mechanism.
Net torque is the magnitude and direction of torque that is left over when you add up the torques that are acting on an object.
If the bar magnet turned then there was a torque acting upon it. Torque is defined as a turning force or moment.
Just as a net force is the vector sum of all the forces acting on an object, a net torque is the vector sum of all torques acting on an object.

That depends on where the axis of rotation is.
M1 = M2 x L1 / L2M1 is the torque setting of the wrench.M2 is the actual torque applied to the nutL1 is the normal length of the wrenchL2 is the extended length of the wrench (Length of wrench + length of adapter)Remember... Torque = Force x Radius
A torque multiplier increases the torque by increasing the length from which a bolt or nut is turned. This process is referred to as "mechanical advantage."
torque = force * lever length torque = 15 * 55 torque = 825 n-cms
