Question

That the 125 N load needs to be placed for the ruler to be balanced

Answer 1

To achieve equilibrium with a 125 N load on a ruler, the torque equation
`(\( \tau = r * F \))` implies r can be any distance, dependent on the ruler's characteristics.

To determine the distance from the pivot point where a 125 N load should be placed on a ruler for equilibrium, we can use the torque equation:

Torque (τ) = distance (r) × force (F)

For equilibrium, the sum of torques must be zero. Let's denote the length of the ruler as L, and the pivot point as the point of rotation.

Torque due to the 125 N load (τ125N):

Torque125N = r125N × 125

Equilibrium condition:

For equilibrium, the sum of torques is zero:

Torque125N = 0

Now, let's solve for r125N:

r125N × 125 = 0

Since Torque125N must be zero for equilibrium, r125N can be any distance. The choice of r125N depends on the ruler's characteristics or any other conditions provided in the question.

The question probable may be:

Determine the distance from the pivot point at which a 125 N load should be placed on a ruler to achieve balance. Include the necessary information about the ruler, such as its length or any other relevant specifications, and consider the conditions for equilibrium.
