Knecht Chapter 20 Review Question

Project 4: 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 colunus 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-A709IGrade 345 - Factor of Safety (FS) 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…

Question Homework : Materials for Oars • Mechanically speaking, an oar is a beam, loaded in bending. It must be strong enough to carry the bending moment exerted by the oarsman without breaking. It must have just the right stiffness to match the rower's own characteristics and give the right 'feel'. The most important, it must be as light as possible. Handle Collar Sleeve Spoon The oar stiffness is measured: a 10 kg weight is hung on the oar, 2.05 m from the collar and the Loom- deflection at this point is measured. A soft oar will deflect nearly 50 mm; a hard one only 30. A rower, ordering an oar, will specify how 'hard' it should be. QUESTION 1. Find material choice 2. Should we change the cross-section from the circular shape to the rectangular shape in order to increase the bending stiffness?

Q1:T shaped Mild Steel beams are widely used in structural fabrication activities, examine the shown M.S. Beam and with required sketches explain how it can be manufactured.

I NEED THE ANSWER ASAP!

Select the correct statement: (assume the replacement beam is of the same shape. Another solution to the problem would be to increase the size of the beam. This is a simplified case, there are many considerations in choosing materials for support beams (flammability, cost, behaviors in different temperatures and humidity environments, brittleness, availability,...) a. The stress on that supporting beam is causing too much strain. We should replace it with a material that has a lower Young's Modulus. O b. The stress on that supporting beam is causing too much strain. We should replace it with a material that has a larger Young's Modulus. С. The strain on that supporting beam is causing too much stress. We should replace it with a material that has a larger Young's Modulus. d. The strain on that supporting beam is causing too much stress. We should replace it with a material that has a lower Young's Modulus.

True or False: ( ) Buckling is the critical failure mode when Euler beams are subjected to very larger compressive stress than the yield strength.( ) Fatigue failure of the structure occurs due to the sudden impact load.( ) The reliability of products always decreases with respect to time or cycles with constant failure rate.

A transverse force applied to a cantilever beam develops bending. Stress is within the elastic range but is too high. Which of the following statements best describes the optimal solution to reduce stress?   A. Increase the length B. Increase the axial moment of inertia C. Reduce the cross-sectional area. D. Change to a stronger material (without changing the dimensions). E. Reduce the height of the beam.
