Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

Learning Goal: To use the vector cross product to calculate the moment produced by a force, or forces, about a specified point on a member. Part A - Moment due to a force specified by magnitude and endpoints The moment of a force F about the moment axis passing through O and perpendicular to the plane containing O and F can be expressed using the vector cross product, Mo =r x F. In a properly constructed Cartesian coordinate system, the vector cross product can be calculated using a matrix determinant: As shown, a member is fixed at the origin, point O, and has an applied force F, the tension in the rope, applied at the free end, point B. (Figure 1) The force has magnitude F = 180 N and is directed as shown. The dimensions are ¤1 = 0.350 m, x2 = 1.90 m, y1 = 2.30 m, and z1 = 1.20 m. What is the moment about the origin due to the applied force F? j M=r x F =|rz i k Express the individual components of the Cartesian vector to three significant figures, separated by commas.

Q2. A 70 kg skier that moves from rest at A is shown in Figure Q2. Suppose friction can be neglected while the direction of the launching velocity at B and the orientation of the underneath ground are 30° and 40° from a horizontal axis x, respectively, determine: (a) the launching velocity of the skier at B using the formulation of conservation of energy. (b) the distance, s where the skier lands at C by considering motion in x and y axes.

In our data run, we zeroed the force sensor at the cart's equilibrium position. Name the total force to stretch the spring F = ky. Name the force to stretch the spring to the cart's equilibrium position F, = ky,. Name the difference in the force to move the cart from the equilibrium position, F. So that F = F, +F, 23. Write the expression for F, in terms of y,, y, and k ?
