Measure the distance r between the pivot point and the point where the force is applied. Determine the angle θ between the direction of the applied force and the vector between the point where the force is applied and the fulcrum. **Multiply r by F and sin θ** and you get the torque.

A convenient way to calculate the magnitude of the torque is to **first determine the lever arm and then multiply it by the force applied**. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. and the magnitude of the torque is τ = Nm.

When studying how objects rotate, it quickly becomes necessary to **find out how a given force causes a change in rotational motion**. The tendency of a force to cause or change rotational motion is called torque and is one of the most important concepts to understand when solving rotational motion situations.

The direction of the torque can be found using the right-hand rule for cross products: **Point your fingers in the direction of the first vector ( ) and your palm in the direction of the second vector ( ); Your thumb is pointing in the direction of the cross product ( )**.

- Torque (lb.in) = 63,025 x Horsepower (HP) / Speed (RPM)
- Power (HP) = Torque (lb.in) x Speed (RPM) / 63, 02
- Torque (Nm) = 5488 x power (kW) / speed (rpm)
- Power (kW) = torque (Nm) x speed (rpm) / 548

**Opening a bottle cap or turning a steering wheel** are examples of torque.

1 : **a force that produces or tends to produce rotation or torsion** a car engine delivers torque to the driveshaft also : a measure of the effectiveness of such a force, consisting of the product of force and the perpendicular distance from the line of action of the force to the axis of rotation.

The magnitude of the torque of a rigid body depends on three quantities: **the applied force, the moment arm vector connecting the point where the torque is measured to the point of application of the force, and the angle between the force and moment arm vectors **.

The basic formula **T = K x D x P** given above takes these factors into account and provides the user with a starting point for establishing an initial target tightening torque.

DETERMINE TORQUE

The general equation for bolt load based on applied torque is **T = KF _{i}D_{b} where K = torque coefficient **. K is a function of the coefficients of friction and boot friction in the joint, and these are based on variables such as surface finish, coatings, etc.

What’s the difference? Put very simply, **torque allows you to feel the sensation of acceleration when you put your foot on the ground, while horsepower is your overall speed and power**. This makes sense considering that horsepower is calculated from torque.

Torque: The torque output of a motor is **the amount of rotational force that the motor develops**. Torque from a small electric motor is commonly measured in either inch-pounds (in-lbs), Newton meters (N-m), or other directly converted units.

The 1800 rpm, 1 hp motor produces **3 ft.** **lbs** of torque at 1800 rpm. The 3600 rpm, 1 hp motor generates 1.5 ft. lbs.

Watt (W) to Torque (Nm) Calculation:

**Motor Torque T _{(}_{Nm}_{)} in Newton meters (Nm) is equal to 9.554140127 times the electrical power P_{(}_{W}_{)} in watts divided by the speed N_{ (}_{rpm}_{)} to rpm**. Example: Calculate the nominal torque that the three-phase motor with 22000 watts and 1490 rpm can develop. T

The most obvious example of torque in action is **using a crescent wrench to loosen a lug nut**, followed closely by a playground see-saw. But torque is also critical to the operation of gyroscopes for navigation and various engines, both internal combustion and electric.
