we can show moment arm as r=torque divide by force.
The Moment Arm, for a force, is the perpendicular distance from an axis to the line of action of the force.
SI unit for moment arm is 1 meter
In a lever, the product of effort and effort arm is called Moment of effort and product of load and load arm is called Moment of load. In general case, as asked in the question, "The Product of force and lever-arm distance is called Moment of Force"the Moment of Force isn't correct its {Torque}
The moment of inertia formula isIxx= bh3 / 12B= base H= height and Ixx = moment of inertia of a rectagular section about x-x axis.
vector
M = [rF] - is a formula for produced moment calculation.
My= As*Fy*Jd As= Area of steel reinforcement (tensile steel only) Fy= yield strength of steel Jd= moment arm
SI unit for moment arm is 1 meter
i dont know why ask

THE PRODUCT OF LOAD AND LOAD ARM IS CALLED MOMENT OF LOAD.
Dimensional formula of moment of inertia = [ML2T0 ]
THE PRODUCT OF EFFORT AND EFFORT ARM IS CALLED MOMENT OF EFFORT.
In order for a force to produce a torque, either all of it, or a part of it (component) must act perpendicular to the moment arm. If, as in your case, all of the force is parallel to the moment arm then the force can not produce a torque. So the answer is; the torque is zero.
The moment of inertia formula isIxx= bh3 / 12B= base H= height and Ixx = moment of inertia of a rectagular section about x-x axis.
vector
because spanner has a longer moment arm and torque depends upon moment arm greater the moment greater will be the torque produced so it is easy to unscrew a tight nut using longer spanner
M = [rF] - is a formula for produced moment calculation.
