QI: Write true or false a- The body is constant when no force effect of this. b- The moment is force x distance. c- Force is vector quantity. d- The force in the engineering dynamics is zero. e- Space is the geometric region for two coordinates and three coordinates. f- Particle is zero dimensions but have weight. g- Acceleration is a scaler quantity. h- We can use tan law to solve the problems. i- We use the plus in the cosine law when the angle between two force. j- Rivet between two plates is extemal force.

1. For each, state whether it is TRUE or FALSE, and support your answer with a few sentences or provide a sketch. In rectangular coordinates the unit vectors change with respect to a) time. b) In cases of uniform acceleration, you could define velocity as a function of time or as a function of position. c) If two particles are moving along the same line, you can find the position of B with respect to A by adding xA+xB. The same relationship is true for velocity and acceleration. A B MAY 124 tv A

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.
