Question 2 : The composite beam consists of a wood core and two plates of steel. If the allowable bend ng stress for the wood is (oaiow )y = 20MPa and for the s(o aienl =130MPA zilow determine the maximum moment that can be applied to the beam. E, =11GPA , E= 200GPA Take: A = 125 mm A mm B = 75 mm M 20 mm- B mm 20 mm Solution : E 200(10" E 1110° The width of steel must be increased to an equivalent width for wood: Page 1 18.182 W. mm
