Bridge question please help?

Question

A 50.0 g bridge 35 cm long is supported at each end and 15 kg are placed on top. Find F1 and F2, find the force exerted by the legs of the bridge. ( it's a triangular bridge). The bridge falls 1.5m sraight down and at max. compresses a spring 0.15.. Find the spring constant.
I know that I have to use components, but I don't know how.

Answer 1

Well, it's going to be tough.
A triangular bridge with legs is hard to imagine.
You didn't put any units on the 0.15 nor locate the spring nor the 15 kg (center)
A very light bridge supporting 300 times its weight in the units given. Correct?
