What is the formula for net torque?
The net torque is therefore τnet=∑i|τi|=160−60+120+10=230N⋅m.
What angle do you use for torque?
Torque Calculation The direction of the torque is given be the right hand rule, which gives a vector out toward the reader in this case. Note that the torque is maximum when the angle is 90 degrees.
How do you calculate F in torque?
The magnitude of a torque about a fixed axis is calculated by finding the lever arm to the point where the force is applied and using the relation |→τ|=r⊥F | τ → | = r ⊥ F , where r⊥ is the perpendicular distance from the axis to the line upon which the force vector lies.
Does angle affect torque?
The magnitude of the torque depends on: Angle between the force and lever arm θ: Directing a force perpendicular to the lever arm increases the torque.
Can a single force produce a zero torque?
If you have an unconstrained point particle, e.g. a ball in empty space, a single force acting on it determines only a uniformly accelerated linear motion, no torque.
Why does torque depend on distance?
Torque is force times distance, so the more distance, the less force needed to achieve the same torque.
Can you have negative torque?
Negative torque does not exist, just like negative force and negative energy don’t exist. (Don’t get me started on quantum mechanics) It’s an absolute value, meaning it can only be positive. The direction, however, can vary. Negative torque does not exist, just like negative force and negative energy don’t exist.
Does torque depend on where the force is applied?
Torque is the rotational equivalence of force. The size of a torque depends on (1) the size of the force applied and (2) its perpendicular distance from the axis of rotation (which depends both on the direction of the force plus its physical distance from the axis of rotation).
Is the torque positive or negative?
Torque is a vector quantity that has direction as well as magnitude. Turning the handle of a screwdriver clockwise and then counterclockwise will advance the screw first inward and then outward. By convention, counterclockwise torques are positive and clockwise torques are negative.
What are the conditions under which torque is zero?
System of Particles and Rotational Motion. Under what condition torque acting on body by a given force is zero? That is, Torque = 0. That is, when line of action of forces passes through the axis of rotation, torque is zero.
Why are clockwise moments considered negative?
Clockwise moments are considered negative when summed with counterclockwise moments because they are opposites of each other, but also because counterclockwise moments are positive since when acting upon an object, they move the object up on the Y-Axis.
