Which of the following is an example of subjective data?

Which of the following properly assesses the 1814 Treaty of Ghent, which ended the War of 1812?

The steel plate with known weight and non-uniform thickness and density is supported as shown. Of the three parameters (CG, CM, and centroid), which one is needed for determining the support reactions? Are all three parameters located at the same point? (CG: Center of gravity; CM: Center of mass)

The magnitude of the moment of force P about point A can be determined by M=Pd. Which is the correct expression of the distance d?

Personal values are best described as:

Determine the force in member EF and indicate whether the member is in tension or compression.

The National Institutes of Health ensure the safety of food and drugs offered to consumers in the United States.

A uniform ladder weighs 20 lb. The vertical wall is smooth (no friction). The floor is rough and coefficient of static friction, μs = 0.8. If the force P is causing tipping of the ladder, what is the normal force on the ladder at point B?  

In the figure, using the conventional cartesian coordinate system in 2-D (right direction is positive x, left direction is negative x and upward direction is positive y, downward direction is negative y, CW negative, CCW positive), it is found that the reaction forces at point A are Ax = -400 N and Ay = -96 N. In this case, what are the internal forces at point C: normal force (Nc), bending moment (Mc), and shear force(Vc);   (Nc, Mc, Vc)?

Under the Articles of Confederation, what power did the national Confederation Congress have?
