      Hasnain Tariq Andy Morales follow the rule of moment arm. moment arm is the perpendicular distance b/w line of action and axis of rotation. In this case we will consider roots as an axis and other part is line of action . According to this rule if Andy Morales apply...  more

      Zarin sadaf snigdha Here Andy is following the laws of Moment. Here the roots are the axis of rotation & the tree is the line of action. If Andy applies force on the axis of rotation the tree will never move as it is the pivot point & Moment will be zero. But if he...  more

      Shadman Chowdhury The answer to this question is quite simple and straightforward. The force exerted (Trying to lift the tree) was, Tension force of rope=Tension force at a certain distance from the End of the rope= Force that would be required to push (lift) the car...  more

      Tanveer Tausif Ratul Andy actually used the theory called-MOMENT.So the question is what is moment?Moment is the measure of the ability of a force to produce rotation/turning effect of an object about a fixed point or an axis.It can be measured by a simple formula which is...  more

      Tanveer Tausif Ratul people were applying 10N force.


      So when they were trying to uproot the tree from the bottom side,which means the applied force was near...  more

      Hasnain Tariq hi Tanveer how you can assume that they need 10 N force to move the tree away . did you know 10 N is actually required to displace mass of 1.02 kg and i think mass of tree is much higher

      Rohan Deb Because of Laws of Moment it was easier to lift the tree away from it roots. We have to apply Total Anticlockwise Moment=Total Clockwise Moment. Suppose the roots of the tree has a moment of 25N/m after falling onto the car. So in order to lift the tree...  more

      Moneera Chowdhury To push the tree up, you have to give a force that is bigger than the tree's weight. At a distance further from the roots, the distance you have to move the tree from the ground to upright is bigger than the distance closer to the roots. To make up for...  more

      Wafeeqa Hoque Mr. Morales implemented the concept of ‘moment’. Moment can be defined as the turning effect of a force around a pivot by the perpendicular/ at right angle distance between the pivot and force applied.
      -Pivot: Is the fixed point over which...  more

      This is basically because the farther you are from the pivot, the lesser force required.

      Abeer Muhammad Andy used what is called the turning effect of a force, also
      called the moment of a force. To understand this, we need to know a couple of
      things:...  more

      Arika Afrin Greater distance from the pivot, less force is required so in this case, the pivot is the root of the tree and if you are close to the pivot which is the root then it will require more force or it will be impossible to lift it up and Mr. Morales went to...  more

      Jawadul Islam Chowdhury Imagine a wrench tightly fitted onto a nut. If you were to move the wrench from the head, a lot of energy would be required to do that. However, if you were to move the wrench from the head side, a lot less energy would be needed to move the wrench. The...  more

      Syeda Anmol Andy used the ideology of moment. Moment of force is the idea to make a body to rotate on a pivot. Moment has a simple rule that is the closer you are to the pivot or the point the more energy you would require to rotate the body. This rule is obeyed by...  more

      Nishat Tamanna Mr. Andy chimed in with the idea of momentum. Momentum is the product of force and the perpendicular distance between the pivot and line of force. He considered providing a force greater than the weight of the tree, but this is only feasible if the force...  more

      Farhan Shahid Andy's idea concerns the effect of moments. The idea about moments is that the further a force acts away from the pivot(the turning point of an object), the more effective it will be in turning the object. For example, the knob of a door is situated the...  more

      Abdullah Masud Mr Andy was able to use the principles of moment in the above scenario. As mentioned in the scenario, the roots of the tree were fixed with the ground so it was a fixed point and a fixed point is called a pivot. This pivot allowed the tree to be removed...  more

      Shaikh Nafisa Binte Fahad Andy told others to help lift the tree from the other side, as the force acting away from the root of the tree made it easier to lift the tree than near the root.
      The car was acting as a pivot here because the weight of the whole tree was on the car. The...  more

      Raheeb Arman Andy uses the idea of moment. Moment of a force is a measure of its tendency to cause a body to rotate on a pivot. Moment justifies that closer you are to the pivot, more force is required to move the object. This law is obeyed by many objects which we...  more
