Find the centroidal moment of inertia about the x axis for the T-shaped area below. The following steps MUST be taken to solve this problem: a. Locate the centroid of each rectangular area relative to a common base axis (10 points) b. Determine the location of the centroid of the composite shape (10 points) c. Find the centroidal moment of inertia about the x axis (15 points)

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?
