Solve the below problem:
Q: Uniform plate ADEH with mass m is connected to the ground with a ball and socket joint at A. It is also held by three massless bars (CE, CH and BH) that have ball and socket joints at each end, one end at the rigid ground (at C and B) and one end on the plate (at E and H). In terms of some or all of m; g; and L find the reaction at A (the force of the ground on the plate) and the three bar tensions TCE, TCH and TBH.
