How we explain varignon's theorem and prove them?
The Principle of Moments, also known as Varignon's Theorem, states that the moment of any force is equal to the algebraic sum of the moments of the components of that force. It is a very important principle that is often used in conjunction with the Principle of Transmissibility in order to solve systems of forces that are acting upon and/or within a structure.Type your answer here...
Why is a seesaw a force multiplier?
A seesaw acts as a force multiplier because it uses the principle of leverage, allowing a smaller force applied at a greater distance from the fulcrum to lift a heavier load positioned closer to the fulcrum. This mechanical advantage is achieved through the seesaw's pivot point, which amplifies the input force based on the ratio of the distances from the fulcrum to the points where the forces are applied. As a result, it enables one person to lift another who may be significantly heavier, demonstrating how the arrangement of forces and distances can enhance lifting capability.
What formula is used in Archimedes' principle?
Archimedes principle - weight of the liquid displaced by the object= buoyant force weight=mass x acceleration due to gravity =volume x density x acceleration due to gravity
Can two electric lines of force intersect each other?
No. If they did, that would mean that at the point of intersection, the force field points in two different directions simultaneously!
Three forces with magnitudes 75 pounds110 pounds and 30 pounds act on an object whats the magnitude?
That all depends on the direction of each force.Examples:If all 3 forces are in the same direction, the net force on the object is 215 pounds in that same direction.If the 30 and the 75 both point left and the 110 points right, the net force is 5 pounds to the right.If the 30 points west, the 75 points north, and the 110 points south, the net force is 46 pounds toward roughly southwest.
