Write a computer program that will analyze a spur gear or helical-mesh gear, accepting ϕ_n , ψ, P_t , N_P, and N_G; compute m_G, d_P, d_G, p_t , p_n , p_x , and ϕ_t ; and give advice as to the smallest tooth count that will allow a pinion to run with itself without interference, run with its gear, and run with a rack. Also have it give the largest tooth count possible with the intended pinion.
