Question

Draw a force diagram of a 23kg box of eel tails being pulled with a rope horizontally across the

bumpy floor

Answer 1

Please find attached, the required force diagram of the 23 kg box of eel tails being pulled with a rope horizontally across the bumpy floor

Step-by-step explanation:

The steps required to draw a force diagram includes

1) The object on which the applied forces act is identified

2) The forces acting on the object are identified by the condition or state of the object, which may be stationary or in motion

3) Specify the object on the diagram using a spot

4) Each of the forces acting on the object (the spot) are added, in vector format, showing both the magnitude and the direction of the forces

The forces acting on the box are;

a) The weight of the box,
`F_w`, acting vertically downwards, with a magnitude given as follows;

`F_w` = Mass of box × Acceleration due to gravity = 23 × 9.81 = 225.63 N

b) The force of friction,
`F_f`, acting in the opposite direction of motion of the box, with a magnitude given as follows;

`F_f` = Weight of the box × Coefficient of friction

`F_f` = 225.63 N ×
`\mu _x`

c) The force pulling the box,
`F_p`, = The mass of the block × The acceleration of the block

The direction of the pulling force = The forward direction of motion of the box.
