Question

States two conditions necessary to maintain the metre rule in the experiment of moment

Answer 1

Answer:

Explanation:

The second condition necessary to achieve equilibrium involves avoiding accelerated rotation (maintaining a constant angular velocity. A rotating body or system can be in equilibrium if its rate of rotation is constant and remains unchanged by the forces acting on it. To understand what factors affect rotation, let us think about what happens when you open an ordinary door by rotating it on its hinges.

Several familiar factors determine how effective you are in opening the door. See Figure 1. First of all, the larger the force, the more effective it is in opening the door—obviously, the harder you push, the more rapidly the door opens. Also, the point at which you push is crucial. If you apply your force too close to the hinges, the door will open slowly, if at all. Most people have been embarrassed by making this mistake and bumping up against a door when it did not open as quickly as expected. Finally, the direction in which you push is also important. The most effective direction is perpendicular to the door—we push in this direction almost instinctively.

Answer 2

Answer:

First Condition of Equilibrium: For an object to be in equilibrium, it must experience no acceleration, implying that both the net force and the net torque on the object are be zero.

The second condition of static equilibrium states that the net torque acting on the object should be zero.
