A motor-driven gear is used to produce forces P1 and P2 in members AB and AC of a machine. Member AC is parallel to the y axis.

(a)    Determine the x and y components of the resultant force vector at A due to forces P1 and P2.

(b)   Determine the t and n components of the resultant force vector. Comment on why the t and n components might be useful to know.
