Why torque is zero when force is applied to point that passes through pivot point?
Torque is defined as the product of the distance from the pivot point, times a force, times an angle function. If any of the three factors is zero, the product is zero. In this case, the distance from the pivot point.
Where should a force be applied to a lever arm to produce the most torque?
Farthest away from the pivot point.
Does a lever pivot on a fulcrum or a torque?
Fulcrum. Torque is the force applied to move the lever
What is a tourque?
Torque is defined as a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis, which is called the pivot point. Let the force acting on it is 'F'. The distance from the pivot point to the point where the force acts is called the moment arm, and is denoted by 'r'.Now, torque, τ = r * F = rFsin ѲHence, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, 'a' being the angle between r and F. We are taking cross product because the variables involved are vectors. Note that the distance in this case is a vector.
What is the name for the pivot point in a lever?
The pivot point of a lever system is called the fulcrum.

Does the center of mass have torque if it isn't a pivot point?
yes
When measuring torque is a two foot-pound measurement the equivalent of two pounds of force applied one foot from the pivot point or one pound of force two feet from the pivot point?
The way torque works, these two cases give the same torque, or twisting force, to the object at the pivot point. To find the torque applied, multiply the force by the distance. Obviously this is the same in the two cases you describe.
A pendulum consists of an object of mass 1.21kg tht hangs at the end of a massless bar a distance 1.28m from the pivot point calculate the magnitude of the torque due to gravity about the pivot point?
The torque is the component of the weight that is perpendicular to the bar. So when the bar hangs vertically down, parallel to the force of gravity, there is no torque. If the bar makes an angle "A" with the vertical then the component of weight perpendicular to the bar would be mgSin(A) and the torque would be mgLSin(A) , where m= 1.21 kg, and L = 1.28m, g=9.8m/ss , so all you need is the angle "A".

A pendulum consists of an object of mass 1.21kg tht hangs at the end of a massless bar a distance 1.28m from the pivot point calculate the magnitude of the torque due to gravity about the pivot....?
The question says nothing about the motion of the pendulum, or about its position at the instant we're supposed to consider, only that it "hangs". If it's just hanging there limp, then the force is acting straight through the pivot, the distance between the line of the force and the pivot is zero, so the torque = R x F is zero.================================================= Did the question mean to say that the 1.28 m is the horizontaldistance between the pivot and the vertical, on account of the bar is slanted ??? If that's the case, why then the vertical force due to gravity is the weight of the bob = m x g = 1.21 x 9.8 = 11.858 N. The magnitude of the torque = |R x F| = 1.28 x 11.858 = 15.178 Newton-Meters.
Deduce an expression for the torque develop by the armature of a dc motor?
he magnitude of torque depends on three quantities: First, the force applied; second, the length of the lever arm[4] connecting the axis to the point of force application; and third, the angle between the two. In symbols:whereτ is the torque vector and τ is the magnitude of the torque,r is the displacement vector (a vector from the point from which torque is measured to the point where force is applied), and r is the length (or magnitude) of the lever arm vector,F is the force vector, and F is the magnitude of the force,× denotes the cross product,θ is the angle between the force vector and the lever arm vector.

How do you calculate braking torque?
To calculate brake torque, multiply force with the distance from the point of rotation. Force is equal to the torsional reaction caused by the brakes, and is also equal in magnitude to the torque exerted by the road.
What 2 things does the moment of a force depend on?
What two factors must be known in order to calculate the moment of a force? Torque = Force * distance Torque and distance must be perpendicular to each other If not you must determine the portion of the torque that is perpendicular.
Does a lever pivot on a fulcrum or a torque?
Fulcrum. Torque is the force applied to move the lever
