large concrete slab height 5.6m, supported at th top by steel beam positioned at angle 42 on the verticle. find length of steel beam
+36916 I will assume this is like a tilt up panel in a wall and the slab is vertical ...thus a right triangle is formed
sin = opposite / hypotenuse
sin 42 = 5.6/hypotenuse
hypotenuse = beam length = 5.6/sin 42 = 8.369 m
