A cantilever beam is reinforced with 4-#9 epoxy coated reinforcing bars, determine the length required of 180° hooks for the epoxy coated #9 bars shown if lightweight-weight concrete is used. Assume side, top and bottom cover to be at least 2.5", f. = 4000 psi and fy = 60,000 psi. Area required = 3.60 in?. Use all the coefficients that apply. Stirrups are not provided along the hooks.
