Determine the minimum horizontal force necessary for 200 lb – Civil Engineering
1.Determine the maximum force (P) that can safely applied to a steel tee section (20 feet in length) with the point loads at 5 feet from each end. Fixed at one end, pin at the other. Answer is 7.2 kips, show me how to get there.
2.A 2-inch by 2-inch solid steel beam (18 inches long) is fixed to the wall at the left to resist applied moment (20,000 lbs-inch). What would the deflection be at the right end? Up or down?
3.Determine the minimum horizontal force necessary for 200 lb man to scale crevice (using his feet and back). The coefficient of static friction between his shoes and his back against the wall is 0.4.
