In general, line resistance = resistivity * line length / (line cross-sectional area).

Check the unit consistency: for the right-hand side, [ohm-m] * [m] / [m^2] = [ohm].

The resistivity of the material should be given. You can measure it with a large chunk of the material using a four-point probe, simplistically speaking. You can also look up the value online.

What is the formula to find resistance force?

The formula to find resistance force is given by R = F/A, where R is the resistance force, F is the force applied, and A is the area over which the force is applied. This formula is often used in physics and engineering to determine the resistance force in various scenarios.


What formula measures force between objects and not resistance?

Force = Pressure x Area


What is the AMA formula of a wheel and axle?

whereR = resistance forceEactual = actual effort force, the force required to turn the wheel.


How do you calculate if the effort force was missing?

If you know the amount of work, and distance, set up an algebraic expression. For instance if the amount of work is 40, and the distance is 2 feet, and you let F= effort force, the equation is 2F=40. You solve by dividing by both sides by 2. So, the effort force is 20.

What is the formula of air resistance?

The formula for air resistance can be calculated using the equation: F = 0.5 * ρ * A * Cd * V^2 Where: F is the air resistance force, ρ is the air density, A is the cross-sectional area of the object, Cd is the drag coefficient, and V is the velocity of the object.


A screw has a pitch of 0.0200 cm. An effort force of 29.0 N is used to turn a screwdriver whose handle diameter is 36.0 mm. What is the maximum resistance force?

To calculate the maximum resistance force, we first need to find the mechanical advantage of the screwdriver. The mechanical advantage is calculated as the handle diameter divided by the pitch of the screw, which gives us 36.0 mm / 0.200 cm = 180. Next, we use the formula for mechanical advantage: MA = Resistance force / Effort force. Plugging in the values, we get 180 = Resistance force / 29.0 N. Solving for the resistance force gives us 180 * 29.0 N = 5220 N as the maximum resistance force.


How are effort force and resistance force different?

Effort force is the force applied to overcome resistance force in order to move an object, while resistance force is the force that opposes the motion of an object. Effort force acts in the direction of motion, whereas resistance force acts in the opposite direction. The ratio of effort force to resistance force is a measure of mechanical advantage in simple machines.


What is the meaning of resistance force?

Resistance force is the force which an effort force must overcome in order to do work on an object via a simple machine. Resistance force, like most other forces, is measured in newtons or in pound-force. Resistance force is used to calculate the work output using the equation: Work output = Resistance force * resistance distance


Is air resistance a pull force or push force?

Yes resistance would be a push force.


are Stress is equal to the force divided by area?

Stress is defined as force per unit area. It is the measure of the internal resistance of a material to deformation under a load. The formula for stress is Stress = Force / Area.
