Answer:
F = 0.3766[lb]
Explanation:
In order to solve this problem, we must perform a static analysis, draw a free body diagram and analyze the forces acting on the yardstick.
In the attached free body diagram we can see these forces, then we can perform a sum of moments at point A of the yardstick.
The horizontal distance can be found using the distance and the angle:
x = 3*sin(37)
x = 1.805[ft] and the middle distance will be 0.902[ft]
For the vertical distance we have:
y = 3*cos(37)
y = 2.395[ft]
Answer:
symbolic solution for the coefficient of friction between the baby and the sled is
Explanation:
From the question we are told that
The mass of the boy is
The mass of the shed is
The mass of the baby is
The maximum acceleration for the baby to stay is a
Generally the frictional force between the baby and the shed is mathematically represented as
Here N is the normal force acting on the baby which is mathematically represented as
=>
Now for the baby not the slip off the shed the frictional force between the baby and the shed must be equal to the the force applied by the child
The force applied by the child is mathematically represented as
So
=>
