Hello, this question is question 10 of exercise 2D in M2 Mechanics by Brian Jefferson. There is no image to go along with it which is causing the majority of my problems.
A uniform rod AB of length 2a and weight W is hinged to a horizontal ceiling at A and is suspended by a light in extensible string BC of length a connecting B to a point C on the ceiling such that angle ABC is 90 degrees. Show that the tension in the string is W Sqrt 5, and find the horizontal and vertical components of the reaction of the hinge on the rod.
