LowlyPion said:T = r X F
So you want to figure the force acting at a perpendicular to the point at interest.
In this case your r X F1 will equal |F1|*h, where h is the distance at which it is acting ⊥ to a line through A.
magma_saber said:i tried that, its wrong. it says the z component. would that make a difference?
magma_saber said:it asks just for the torque for each force that is applied, i.e. F1, F2, F3, ect. After that, it asks for the net torque. for F1 i tried F*h and it was wrong. Would it be F*h*w, since the tail starts at w?
Torque is a measure of the force that causes an object to rotate. It is calculated by multiplying the force applied to the object by the perpendicular distance from the point of rotation to the line of action of the force.
The z component of torque is the component of torque that is perpendicular to both the force and the distance vector. It is also known as the cross product of the force and distance vectors.
The z component of torque can be calculated by taking the cross product of the force vector and the distance vector. This is done by multiplying the magnitude of the force by the magnitude of the distance and then multiplying it by the sine of the angle between the two vectors.
The z component of torque is important because it determines the direction of rotation for an object. If the z component is positive, the object will rotate in a counterclockwise direction, and if it is negative, the rotation will be clockwise.
The z component of torque is used in many real-world applications, such as engineering, physics, and mechanics. It is essential for understanding the stability and balance of structures, calculating the movement of objects, and designing machines and mechanisms.
