A 2.5 inch diameter solid aluminum post is subjected to a horizontal force V = 9 kips, a vertical force P = 20 kips, and a torque T = 4 kipLaTeX: \cdot⋅ft, acting in the directions shown. The distance from the cross-section containing Points H and K to the top of the post is L = 3.5 in. The yield strength of the aluminum is 50 ksi, and a minimum factor of safety of 1.67 with respect to yield is required. Determine the state of stress at Point K with respect to the x-y-z coordinate system shown. You should be aware that if one or more of your section properties from Question 1 are incorrect or if one or more of your force and moment components from Question 2 are incorrect, then one or more of your stresses in Question 3 will also be incorrect. This is exactly the same way a paper exam is scored. Also, just as in a paper exam, you receive partial credit for correct section properties and/or correct force and moment components from Questions 1 and 2 even if your stresses in Question 3 are incorrect.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
