Questions 16 through 20 (4 points each): A beam is made by gluing five 2in by 12in boards together with construction adhesive. A transverse load Vis applied to the beam as shown. Answer the following questions about this system. 16) The generic formula for the average shearing stress for a transversely loaded beam is Tave =VQ/It. To determine the shear along glue joint B, what value would you used for I? a) 64in b) 496in c) 500in 1000in+ e) 4000in V A B 17) To determine the shear along glue joint B, what value would you used for Q in the generic formula Tave =VQ/It? a) Oin b) 72in c) 96in d) 120in e144in 18) To determine the shear along glue joint B, what value would you used for t in the generic formula Tave =VQ/It? a) Oin b) 2in c) 4in 19) The glue joint that is mostly likely to fail is d) 10in e12in a) joint A joint B c) joint A and B are equally likely to fail 20) The adhesive can support a maximum shear stress of 6psi. Of the loads listed, which is the largest value of that the beam can support without failing (less than or equal to the maximum). 300 lbs b) 600 lbs c) 900 lbs d) 2000 lbs e) 10,000 lbs
