Find the moment of inertia about the centroidal xx and yy axis of structural member with cross-sectional dimension of 100 × 75 × 6 as shown below.

For a 2D truss with 10 nodes, only 4 nodes are supported and they are all pinned. How many Degreesof Freedom of this model are NOT constrained?

Calculate the value of F and the value of theta θ so that the resultant of the forces is 1200 lb downward

Solve the magnitude and position of the missing force, make sure to do it in step by step manner and make sure to illustrate properly For the given beam shown. There are three forces acting on the beam and the third force is missing, if the resultant of these three vertical forces is 13.6 N acting up at 3 meters to the right of A. Determine the magnitude and position of the missing force.
