The figure shows a uniform beam of mass m pivoted at its lower end, with a horizontal spring attached between its top end and a vertical wall. The beam makes an angle è with the horizontal.

Question

(a) Find expression for the distance d the spring is stretched from equilibrium. (Use any variable or symbol stated above along with the following as necessary: k and g.)
d =

(b) Find expressions for the components of the force exerted by the pivot on the beam. (Use the following as necessary: m, k, g, and è.)

Rx

=

Ry

=

Answer 1

a) d= (mgcos(θ))/(2ksin(θ)

b) Ry = mass * gravity
