A 6.96.9 mm long simply supported wood beam carries a uniformly distributed load of 10.810.8 kN/mkN/m, as shown in Figure A.  The cross-sectional dimensions of the beam as shown in Figure B are b=195b=195 mmmm, d=490d=490 mmmm, yH=80yH=80 mmmm, and yK=158yK=158 mmmm.  Section a–a is located at x=1.4x=1.4 mm from B.

(a) At section a–a, determine the magnitude of the shear stress in the beam at point H.

(b) At section a–a, determine the magnitude of the shear stress in the beam at point K.

(c) If the allowable shear stress for the wood is 950950 kPakPa, what is the largest distributed load ww that can be supported by the beam?

A6.9 m long simply supported wood beam carries a uniformly distributed load of 10.8 kN/m, as shown in Figure A The cross-
sectional dimensions of the beam as shown in Figure B are b = 195 mm, d = 490 mm, y = 80 mm, and yx = 158 mm. Section a-a
