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 with the horizontal.
A beam of mass m is angled up and to the right at an angle of above the horizontal ground. The beam is attached at its lower end to a pivot that allows it to rotate about an axis that points out of the page. The right side of a spring labeled k is attached to the free end of the beam, and the spring extends leftward, fixed to a vertical wall at its left end.
(a) Find an 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 =
Incorrect: Your answer is incorrect.
(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 . Assume the positive x-direction is to the right and the positive y-direction is upward.)
Rx =
Incorrect: Your answer is incorrect.
Ry =
Incorrect: Your answer is incorrect.
