I need the answer as soon as possible 3m 3 m -2 m2 m-13. If the beam is subjected to a bending moment of M = 50 kN. m, determine the maximum bendingstress in the beam.200 mm20 mm300 mM.20 mm20 mm14. A steel beam with overhanging ends and wide-flange cross section is supported as shown in thefigure. The beam carries a uniform load of intensity q = 115 kN/m on each overhang. Assumingthat the section modulus of the cross- sectional area is S = 6.78 X 10° mm', determine themaximum bending stress omax in the beam due to the load q. also find the maxim deflection-115 KN/mq-115 kN/m3m-6 m15. A simple beam AB with span length L = 3.5 m carries a uniform load of intensity q= 6.4 kN/m(see figure). Calculate the maximum bending stress omax due to the load q if the beam has arectangular cross section with width b = 140 mm and height h = 240 mm. also find the maximumdeflection16. The beam is made from three boards nailed together as shown. If the moment acting on the crosssection is M = 600 N. m, determine the resultant force the bending stress produces on the topboard.25 mm150 mm-20 mm200 mm M=XI N-m20 mm17. An element in plane stress is subjected to stresses o, = 50 MPa, ay= 30 MPa, and Tyy= 20 MPa,as shown in the figure. Determine the stresses acting on an element oriented at an angle 0= 50°from the x axis. Also find the principal plane and principal stresses Solve with Both graphical andmathematical techniques30 MPs-50 MPs-20 MP18. At a particular point in a machine the material is in biaxial stress with (ox = 14 MPa and (oy =-56 MPa (see figure). What is the orientation of an inclined plane through the point such that thenormal stress on the plane is zero? Sketch a stress element having that plane as one of its sidesand show all stresses acting on the element.56 MPs14 MP
