7.22 Casing with an ID of 10.05 in. and a strength in tension of 450,000 lbf in the joints and 629,000 lbf in the pipe body is being suspended from the surface while being cemented. If the effective weight of the casing being sup- ported is 240,000 lbf and a safety factor of 1.4 is desired, how much surface pump pressure can be applied safely to displace the cement? The casing burst is rated at 3,130 psi (for zero axial stress).

Design engineers in many situations must justify their selection of beams and pin-ended columns used in various machines. Your role in a mechanical design company that manufactures gearbox and gearbox mounting platform is to analyses the rolled steel beams and columns under study. Your manager asked you to properly select one rolled steel beam and one rolled steel column for the design and to provide your justification of this selection, if the following design requirements are given: Beams and columns are made of ASTM-A709/Grade 345 Factor of Safety (F.S) is 1.4 Buckling Euler conditions must be met. Beams are subjected to 50 kN axial force. Beam (A) has radius of 10 mm. Beam (B) has radius of 5 mm. Column (A) is subjected to 15 kN axial force. Column (A) has length of 1.5 m and radius of 10 mm. Column (B) is subjected to 15 kN axial force. Column (B) has length of 1.5 m and radius of 13 mm. Note: Column critical load must be determined (based on Euler theory caleulations must be…

(13) A spring has an overall length of 44.0in & sustains a load of 15,000lb @ its center. The spring has three full-length leaves & 15 graduated leaves with a central band 4.0in wide. All leaves are to be stressed to 60,000psi when fully loaded. The ratio of total spring depth to width is to be approximately 2.0. Determine: (a) the width & thick ness of the leaves; (b) the initial space that must be provided between the full length & the graduated leaves before the band is applied; (c) What load is exerted on the band after the spring is assembled?

Problem 1: For the truss under the following 3 loading conditions, determine the minimum cost of each truss based on the following: Wood (popsicle sticks) - $100/stick • Cable (thread) - $10/section Please note that all members of the truss are the same length. Given this information, it doesn't matter what length you use, or what "X" is, but if it helps, just make up numbers, i.e. length of 5" and X of 10lbs. In class we will be using members that are approximately 6" long and weights that are approximately % Ib, although on the weights we can just add more to get the desired effect. Come to class with design in hand prepared to assemble the 3 different trusses to test with loads. A) x (lbs) B) x (lbs) x (lbs) x (Ibs) C) x (Ibs) 2x (Ibs)
