  2. Calculating Normal Force on a Student Riding a Ferris Wheel

    www.physicsforums.com/threads/calculating-normal-force-on-a-student-riding-a...

    At the top of the Ferris wheel, the normal force from the seat on to her body has a magnitude of 567 N. To find the magnitude of the normal force at the bottom of the Ferris wheel's arc, the equations Ntop + mg = m (v^2/r) and Nbot - mg = m (v^2/r) can be used. However, it is important to note that the signs for the forces must be carefully ...

  3. Normal force on a banked curve? - Physics Forums

    The formula for calculating the normal force in a banked curve with friction is: N = mg + mv 2 /r - μmgcosθ, where N is the normal force, m is the mass of the object, g is the acceleration due to gravity, v is the velocity of the object, r is the radius of the curve, μ is the coefficient of friction, and θ is the angle of the incline.

  5. Calculation of force from deceleration? - Physics Forums

    www.physicsforums.com/threads/calculation-of-force-from-deceleration.535359

    To calculate force from deceleration, you need to know the mass of the object and the rate of deceleration. The formula used is F = ma, where F is force, m is mass, and a is acceleration. If deceleration is given in units of meters per second squared (m/s^2), then the resulting force would be in newtons (N).

    The Davis Coefficients seem to be for only the locomotive. A = 1070 seems ok, 1070 N rolling resistance with a normal force of 850kN is a drag coefficent of 0.00125. I can't seem to find any realistic values for B. C is from the drag equation with a Cd of 1.0. and a frontal area of 12.9 m^2.

    In order to calculate the normal force, you will need to use the equation F N = mgcosθ, where F N is the normal force, m is the mass of the object, g is the acceleration due to gravity, and θ is the angle between the object and the surface it is in contact with. What is the purpose of calculating the normal force in an equilibrium lab?

  8. How Do You Calculate the Force Required to Pull Out a Pin? -...

    www.physicsforums.com/threads/how-do-you-calculate-the-force-required-to-pull...

    To start, we can use the formula F = μN, where F is the force required to pull the pin, μ is the coefficient of friction between the pin and the surrounding materials, and N is the normal force acting on the pin. Without knowing the specific materials being used, we cannot accurately determine the coefficient of friction.

    Yes, the normal force changes during different phases of a push-up. At the beginning of the push-up when the body is close to the ground, the normal force is higher because the weight of the body is closer to the hands. As the body moves away from the ground, the normal force decreases. 4. How can normal force be increased during push-ups?

    www.physicsforums.com/threads/calculating-the-force-of-applied-by-a-vise-jaw...

    Yes, the force applied by a vise jaw can be too high and can potentially damage the object being held. It is important to use the appropriate clamping force for the specific object to prevent any damage. It is recommended to use a torque wrench to ensure the correct amount of force is applied to the vise handle.

    Oct 13, 2009. Engine Force Power Radius Rpm Wheel. In summary, the equation used to calculate the engine force in a car is: P=30*Tw/ (rpm*r*pi). This equation assumes that there is no friction or drag, and that the car is at a standstill. It seems that the equation may not be accurate, as it underestimates the acceleration of a car.
