While cutting a piece of paper, a person exerts the two indicated forces on a paper cutter. Reduce the two forces to an equivalent force-couple system at corner O and then specify the coordinates of the point P in the x-y plane through which the resultant of the two forces passes. The cutting surface is 28" x 28". 30 lb 13" A 4" 5 lb 1"

Explain Kinematic and Static Indeterminacy for beams, frames and trusses.

For the 2d coordinate system below, complete the following: a) Break up the force vector into Fx and Fy components; show these components on the figure. Add a superscript to each component to indicate whether they are acting in the positive (+) or negative (-) direction b) Draw a position vector from the origin (0) to the tail (point a) of the force vector c) Break up the position vector into rx and ry components; show these components on the figure Add a superscript to each component to indicate whether they are acting in the positive (+) or negative (-) direction d) Calculate the "moment" of force F about the origin by multiplying F times its perpendicular distance from the origin (ry), and add the product of Fy times its perpendicular distance from the origin (rx). Assume that a counterclockwise rotation about the origin is a "positive" moment. Think of rx as a string connected to the origin. If you pull the string in the direction of d, will that cause a clockwise (-) or…

Problem 4: The two bars can deform elastically. They are pinned at point B. The length of AB is 400 mm, length of BC is 250 mm, areas of cross- section of AB and BC are both equal to 35 square millimeters, and modulus of elasticity for material of the bars is the same, and equal to 250 GPa. Angle between AB and the horizontal is 30 degrees. Showing proper coordinate system (positive and negative directions), a. Consider the first figure below. A vertically downward force Facts at pin B. If the horizontal component of the displacement of B is 0.25 mm, determine the magnitude of the force applied, the vertical component of the displacement of B, and the net displacement of point B due to the elongation of bars AB and BC. Show all work and figures clearly. B F b. Now, consider the second figures, where there is a leftward force of magnitude F = 2500 N acting at pin B. Determine the horizontal and vertical components of the deflection of point B, as well as the net deflection of point B. F…

Learning Goal: To replace force-couple systems with an equivalent force by specifying the magnitude and direction of the equivalent force and the location where the force needs to be applied. Certain force-couple systems can be replaced by a single force. The requirement is that the lines of action of the resultant force, FR, and the resultant couple moment, (MR)o, are perpendicular to each other. This is equivalent to saying the following types of force systems can be simplified to a single force: Figure F₂ X F₁ 3 ft A B 2 ft < 2 of 3 C
