solve this question a uniform plan of length 5meter and mass 1kg support 2 masses of 500gram and 300 gram are shown in the figure below determine the meter of gravity in the figure below
To determine the meter of gravity in the figure, we need to calculate the weighted average of the distances of the masses from the fulcrum.
Let's label the distances from the fulcrum to the masses as follows:
- Distance of the 500g mass from the fulcrum: d1
- Distance of the 300g mass from the fulcrum: d2
Since the plank is uniform, its mass is evenly distributed along its length. Thus, we can consider its center of mass to be at its midpoint, which is 2.5 meters from the fulcrum.
Using the principle of moments, we have the equation: (mass1 * distance1) + (mass2 * distance2) = (total mass * center of mass)
Substituting the given values, we get: (0.5kg * d1) + (0.3kg * d2) = (1kg * 2.5m)
Simplifying the equation, we have: 0.5d1 + 0.3d2 = 2.5
Since the equation has two variables, we need another equation to solve for both d1 and d2. However, the figure is mentioned to be shown below, but it is not provided as part of the question. Without the figure or any additional information, we cannot determine the specific distances of the masses from the fulcrum or the meter of gravity.
