Solving the Problem: Lever & Metal Wedge in Water

[alibaba2]

hi..
i have a problem that i need to solve..
in the attached mage, there is a submerged object in water cousing na upward lift force of 100kg. above it is a lever with a weigh attached to it weighing at 90kg. wll this weight difference be enough to move the metal wedge from point a into point d, provided that the wedge is attached to a rope that will slide it along the yellow surface as it goes up out of the water.

I Think That It Would All Have To Do With How Hard Are You Pulling The Rope.

Hello,

Based on the information provided, it seems that you are trying to determine if the weight difference between the submerged object and the lever with the attached weight will be enough to move the metal wedge from point A to point D. In order to solve this problem, we need to consider a few factors.

Firstly, we need to determine the buoyant force acting on the submerged object. This force is equal to the weight of the water displaced by the object, which in this case is 100kg. This means that the upward force acting on the object is 100kg.

Next, we need to consider the downward force acting on the lever. The weight attached to the lever weighs 90kg, which means that the downward force acting on the lever is also 90kg.

Now, in order for the metal wedge to move from point A to point D, the downward force acting on the lever must be greater than the upward force acting on the submerged object. This is because the rope attached to the wedge will be pulling it upwards, against the force of the buoyant force.

Therefore, based on the information provided, it seems that the weight difference between the submerged object and the lever with the attached weight will be enough to move the metal wedge from point A to point D. However, there may be other factors at play that could affect the movement of the wedge, such as the friction between the wedge and the yellow surface.

I hope this helps to solve your problem. If you need further assistance, please provide more information and we can continue to work on finding a solution. Keep up the scientific inquiry!
