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.

Why are the beams that are short and carry large loads, especially those made of wood, are first designed to resist shear?

How is it helpful to sketch the deflected shape of a beam, which is represented by its elastic curve?

The design of an aircraft fuselage skin requires sufficient strength and stiffness in both the longitudinal and hoop direction. Based on this information alone, which of the following material options would be the best option? A) Aluminum 2024-T3  B) Unidirectional glass/epoxy laminate      Which of the statements below on the Euler buckling load is correct? A) If the axial load increases, the Euler buckling load will go up. B) If the axial load decreases, the Euler buckling load will go up. C) If the lateral load increases, the Euler buckling load will go up. D) If the lateral load decreases, the Euler buckling load will go up.   Is the following statement true or false: A structure does not need to break (ie: fracture) in order to fail.   Select whether the following statement is true or false: Structural safety is solely the responsibility of the aircraft manufacturer and the airworthiness authorities.   Select whether the following statement is true or false: Damage tolerance is…

Please explain

Solution should be neat and clear , Please solve in Handwritten format only. (Avoid typed answer)

Bending: Show all Equations Used! Consider a cantilevered, rectangular beam subjected to a load pro- duced by a 1 kg point mass at the (free) tip of the beam. Assume that beam material is made of Aluminum and that the beam is 11 in. long, 1 in. wide and 1/8 in. thick. 1. Based on Euler-Bernoulli beam theory, determine the deflection (in milimeters) of the beam. 2. Determine the longitudinal stress (in MPa), longitudinal strain and transverse strain at the root of the beam.

This my question

Does the elastic curve represent the centerline deflection of a beam or shaft?

Discussion: 1. Was there good agreement between the theoretical predictions (dthe) and the experimentally measured (dexp ) deflection? Why?

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…

Task 3 (a) A beam is to be fitted in a box of length of 2 m, width of 15 cm and height of 20 cm. Choose a beam and specify its parameters, dimensions, at least two loads and support conditions logically so that it can deflect freely to the maximum limit. (b) Will the beam designed in part (a) withstand the stresses. Explain.

How can the elastic curve for a beam be established?

How can we determine the shape of a fully stressed, simply supported beam that supports a concentrated force at its center?

A wood composite was created to enhance the property of the common wood (control). Both samples underwent compression loading test. The result is shown in the accompanying figure. Which of the statement below is true? The elasticity of the wood composite is far better than the control The wood composite exhibit better resistance against deformation The wood composites showed a deformation behavior generally similar to that of untreated wood. After the yield point the composites showed an initially abrupt and then steady decrease in compressive stresS All of the above
