A. spring of force constant k = 600 N/m is attached to end B as shown in Fig. To keep the rod horizontal, its end A is tied with a thread such that the spring is B elongated by 1 CM. Calculate reaction of support P when the thread is burnt.

Figure shows a vertical force applied tangentially to a uniform cylinder of weight Fg. The coefficient static friction between the cylinder and both surface is 0.500. In terms of Fg find the maximum force P that can be applied that does not cause the cylinder to rotate.
