Transcribed Image Text:Question 2
You are holding a thin and weightless bar on your head (see figure 2.1). On the
extremity A, the bar is attached to an elastic spring with unstressed length of 1 m and
spring constant, k = 50 N/m; on the other extremity D, the bar is against a wall. On
point C, a force F is applied, forming a 45-degree angle with the bar. Assign the
length AE according to the height of your body.
(a) What is the magnitude of the force F for the bar to rest horizontally?
(b) If the force F was removed, what support would you need in D in place of the
wall, in order to keep the bar at rest horizontally? Justify your suggestion(s).
State and justify your assumptions and comment on your solutions.
