3. A 60 pound force is attached to the 90° weightless bar ABCD at point B as shown below. The bar is attached to the z axis at A and to the x-y plane at D by ball & socket joints. A cable EC attaches the bar to the y axis as shown. Determine the tension in cable EC. You might want to project something. Note that the ABC part of the bar lies in the x-z plane; that is, it is parallel to the x-axis. Hint: The answer is an integer between 10 and 50. 23" 10" 4" 6" 10" T = 60 lbs in

Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.
