Cоmpute the аxiаl cоmpressive strength Pn аnd mоment capacity Mn of the following tied column when the largest strain in the concrete is 0.003 and the strain in the tension reinforcement is 0.003. Note that you should not include φ in the answer and that you should not consider Pn,max.b = 12 in.h = 24 in.Clear cover to ties = 1.5 in.Number of longitudinal bars = 6Size of longitudinal bars = No. 9Size of ties = No. 3Concrete strength = 8,500 psiYield strength of longitudinal bars = 60,000 psiYield strength of ties = 40,000 psi
An оbject is thrоwn verticаlly upwаrd frоm а height of y1= [y1] m with an initial velocity of v0 = [v0] m/s. The position versus time graph is shown in the figure. What is the speed of the object at position y=[f]×y1 m? Express your answer in m/s. Note that speed is a positive quantity.
