Concept explainers

Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.

Question

The director of the swimming club runs an experiment by examining the impact of 11
factors on average race times across 6 swimming tournaments (6 experimental runs).
(Choose all that are true)
The full model should be fit as the higher order interactions are likely to matter
and there are sufficient degrees of freedom for it.
The design is a supersaturated design because the number of factors is greater
than the number of runs - 1.
Backwards selection should be used to determine which factors significantly
impact race times as model refinement will be needed.
Forwards selection should be used to determine which factors significantly
impact race times as model refinement will be needed and there are insufficient
degrees of freedom to fit the full model.

Assuming simple harmonic motion, determine the magnitudes of the velocity and acceleration of the bob after the pendulum has been in motion for 1.65 s. The magnitude of the velocity of the bob after the pendulum has been in motion for 1.65 s is 82699 ft/s.

Hello Good Evening Sir,I have a question in my homework related structural statics lesson. The following below is my question. Please advice. Thank you so much Regards,Yusuf
For the following concentration expressions, indicate whether they are uniform or nonuniform and in how many dimensions (OD, 1D, 2D, or 3D), and steady or unsteady. Then for the following control volume and origin, and table of constants, use Excel or Matlab to graph profiles that show how concentration changes within the control volume and over time to a limit of 20 for the following: C(x,0,0,0), C(0,y,0,0), c(0,0,z,0) and C(0,0,0,t). On each graph, show which parameters are held constant, the CV boundaries, and the point where all four plots overlap. 20 C(x=0) 10 a 0.0001 b 0.001 20 0.01 y k 0.1 100 All of the following functions are C(space, time) and so not necessarily just x as suggested. a.
