% Program cable.m % % Purpose : % To calculate the connection poin that results in % minimum tension on a cable. % % Define variables: % dist -- Distance to attachment (ft) % lc -- Cable length (ft) % ii -- Index variable % lp -- Pole length (ft) % saved_dist -- Save attachment distance % saved_tension -- Saved tension % tension -- Tension on cable % weight -- Weight of object (lbs) % Initial values lc = 8; lp = 8; weight = 200; % Calculate tension at 0.1 ft dist(1) = 1.0; tension(1) = weight * lc * lp / (dist(1) *sqrt(lp^2 - dist(1)^2) ); % Save initial values for comparision saved_dist = dist; saved_tension = tension; % Calculate for other values between 1 and 7 ft
