A metal cylinder of mass ? = 5 kg with a coaxial hole is sliding horizontally on a metal rod. A spring with spring constant ? = 500 N/m is attached to the cylinder. The other end of the spring is attached on a table at a vertical distance of ℎ = 0.3 m below the cylinder. The spring has an equilibrium length of ?_0 = 0.5 m.
a) What is the horizontal position ?0 of the cylinder when the spring is at its natural equilibrium length of ?0 = 0.5 m? Define the attachment point of the spring on the table as position ? = 0.
b) What is the length ? of the spring when the cylinder is at any given position ??
c) Draw a free-body diagram of the cylinder.
d) Show that the horizontal force from the spring on the cylinder is: ?? = −?? (1 − ?0 √? 2 + ℎ 2 )
