How does a freebody diagram tell you about the net force on an object

We have to take the two axes of coordinates, the X axis & the Y axis, and perform the equation of sum of forces on each of the X & y axes. In order to find the value of the respective forces. We can also perform summations of moments around a given point to find unknowns in deduced equations.

Explanation:

A free body diagram gives us a summary of the forces acting on a body. These forces can be equal to zero. Or equal to the product of its mass by acceleration.

Although in some cases special attention should be paid to the movement of the body by such forces, for example if the movement is at constant speed, the acceleration will be equal to zero. Therefore the sum of forces will be equal to zero when the speed is constant.

Finally we have to take the two axes of coordinates, the X axis & the Y axis, and perform the equation of sum of forces on each of the X & y axes. In order to find the value of the respective forces.

We can also perform summations of moments around a given point to find unknowns in deduced equations.

In the attached image we can see a beam which is subjected to loads, and performing a summation of moments around the pivoting point equal to zero (the beam is in balance) we can find the value of force F.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
