Question

Hello, I'm having hard time understanding why from symmetry it can be determined that forces C and E do not have x-components.

4/91 Determine the force P exerted on the twig G. Note
that there is a horizontal line of symmetry for the
handles, but there is no line of symmetry for the
jaws.
