2020 F = ma Exam B — Question 18

An extendable arm is made from rigid beams free to pivot around the dots shown. Spring 1, with equilibrium length L1 , is attached between points A and C while spring 2, with equilibrium length L2 is attached between B and D. The system is allowed to come to equilibrium. In equilibrium, what is the ratio of the tension in spring 1 to the tension in spring 2? spring 2 A B C D A B C spring 1
