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?  

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

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)?

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

In the figure, beam is attached at point A by using a smooth pin. What is the magnitude of the internal force Nc at point C?
