What is the magnitude of the force needed to keep a 60 Newton rubber block moving across?

A force of μk⋅60N is needed to keep a 60-newton rubber block moving across level, dry asphalt in a straight line at a constant speed.

What is the magnitude of the force of friction between a moving 60 Newton rubber block on a straight and level dry asphalt surface?

40.2 N.

What is the magnitude of force you must apply to keep the crates moving with constant velocity?


How do you find the magnitude of the frictional force?

The magnitude of the force of kinetic friction acting on an object is fk = μkN, where μk is the coefficient of kinetic friction. For most surfaces, μk is less than μs.

How do you find FN?

The weight of an object equals the mass of the object multiplied by the acceleration of gravity. Multiply the two values together. In order to find the normal force, you need to multiply the weight of the object by the cosine of the angle of incline.

What is FN equal to?

normal force

How do you determine tension?

Tension Formulas – How to Calculate Tension Force

  1. Tension can be easily explained in the case of bodies hung from chain, cable, string etc.
  2. T = W ± ma.
  3. Case (iv) If the body moves up or down with uniform speed, tension; T = W.
  4. T=m(g±a)
  5. As tension is a force, its SI unit is newton (N).

Does higher string tension mean?

Most players are familiar with the general principle that low tension gives more power and high tension gives more control. The lower tension strings stretch more during impact and thus store more energy. When the ball rebounds from the racquet, more energy is returned, so it leaves with a higher speed.

How do you find the tension in a rod?

Use the rules of trigonometry to find the adjacent and opposite sides, which will be the horizontal and vertical components of the force. To find the resultant tension, add up the total forces on the rod in the horizontal and vertical directions.

How do you find tension from mass and angle?

You are given the max tension, so use the above to find the max mass. Ans: sin(10degree) x 1000 x 2= max weight of box Just divide the weight by 9.81 gravity to get mass and youre done.

How do you find tension in a rope with acceleration?

The tension on an object is equal to the mass of the object x gravitational force plus/minus the mass x acceleration.

Where is tension in a rope tug of war?

Tension Equation for Team1: The forces acting on Team1 are – F1(pull by the team) and + T. F1 is negative because it is opposite to the direction of the net force. Tension is positive because it acts in direction of the net force. The net force on team1 is the sum of the forces.

What is tension on a string?

In physics, tension is described as the pulling force transmitted axially by the means of a string, a cable, chain, or similar one-dimensional continuous object, or by each end of a rod, truss member, or similar three-dimensional object; tension might also be described as the action-reaction pair of forces acting at …
