Starting with the column in Problem 1, perform enough additional calculations to determine the effects of increasing fc from 500
0 to 8000 psi on column capacity at both high and low axial loads. Assuming that a compressive strength of 8000 psi is appropriate for the lower stories of a high-rise structure, would you recommend using concrete with fc = 8000 psi for the columns supporting all stories within the building? Use your analysis to support your answer.

Answer:
Velocity components
For Acceleration components;
Explanation:
We are given:
We first need to find the radial position r of washer in x-y plane.
Therefore
r = 500 mm
To find length along direction OA we have:
Therefore, the radial and vertical components of velocity will be given as:
Where Q is the angle between OA and vector r.
Therefore,
•
•
The radial and vertical components of acceleration will be:
Therefore we have:
