Question

Груз массой 100 кг удерживают с помощью горизонтального рычага, прикладывая вертикально направленную силу 500 Н, плечо которой равно 1 м. На каком расстоянии от точки опоры находиться груз?

Answer 1

F=P
X=L
X=FL
    mg
P=mg
x=fl
   mg
x=500*1= 0,5
  100*10
ответ 0,5

Answer 2

Calculation of the Distance from the Point of Support

To determine the distance from the point of support at which the weight of 100 kg is being held using a horizontal lever and a vertically directed force of 500 N with a moment arm of 1 m, we can use the principle of moments. The principle of moments states that the sum of the clockwise moments is equal to the sum of the counterclockwise moments.

Let's denote the distance from the point of support to the weight as 'x'. The clockwise moment is given by the weight of the object multiplied by its distance from the point of support, while the counterclockwise moment is given by the applied force multiplied by its moment arm.

Using the principle of moments, we can set up the equation:

(Weight of the object) × (Distance from the point of support) = (Applied force) × (Moment arm)

Substituting the given values:

(100 kg) × (x) = (500 N) × (1 m)

Simplifying the equation:

100x = 500

Solving for 'x':

x = 500/100 = 5 m

Therefore, the weight of 100 kg is being held at a distance of 5 meters from the point of support
