Answer:
Explanation:
Let:
We need to know for which value of the function
is equal to
:
Therefore, we need to solve for the previous equation for :
Replacing the values of and
:
Subtract 4 from both sides:
Multiply both sides by -1
Divide both sides by 3:
Therefore the value of for which
is
.
Verify the result:
Explanation:
It is given that,
When the front wheels are over the scale, the weight recorded by the scale is 5800 N, F₁ = 5800 N
When the rear wheels are over the scale, the scale reads 6500 N, F₂ = 6500
The distance between the front and rear wheels is measured to be 3.20 m, x₂ = 3.2 m
We need to find the location of center of mass behind the front wheels. Let the center of is located at a distance of x₁. Thus balancing the torques we get :
On solving the above equation we get, x₂ = 1.69 m
So, the center of mass is located at a distance of 1.69 meters behind the front wheels.
