Explanation:
Taking moment along point A

Also normal stress is given as 100 psi
Now

The minimum diameter of the stick to bear the normal stress as 100 psi is 0.1785 in.

Answer:
v = 12.12 m/s
Explanation:
Given that,
The mass of the cart, m = 75 kg
The roller coaster begins 15 m above the ground.
We need to find the velocity of the cart halfway to the ground. Let the velocity be v. Using the conservation of energy at this position, h = 15/2 = 7.5 m

So, the velocity of the cart is 12.12 m/s.
