Question

What is the equation for the x axis of this FBD

Answer 1

To find:

The equation for the given FBD.

Step-by-step explanation:

The net force acting on an object is given by the sum of all the forces acting on the object.

Thus the net force acting on the given object in the vertical direction is given by,

`F_(net)=F-f\text{ }\to\text{ \lparen i\rparen}`

From Newton's second law, the net force acting on an object is given by,

`F_(net)=ma\text{ }\to\text{ \lparen ii\rparen}`

Thus from equations (i) and (ii), the equation for the given FBD is given by,

`F-f=ma`

Final answer:

Thus the correct answer is option C.
