Problem 6 (20 points) The beam is made of 3 boards nailed together as shown in the figure. If the moment acting on the cross section is M = 10 kip-ft, determine i) the maximum resultant force acting on the top board A of the beam due to the bending stress induced by the moment. ii) The resultant force acting on the entire web (board B) of the beam due to the bending stress induced by the moment. $I_{NA} = 967.5 in^4$

Question 2 4 pts Let $f(x)$ be a continuous function, increasing on the interval $[a, b]$ and let $R_n$ be a Riemann sum corresponding to $[a, b]$ subdivided into $n$ subintervals with sample points equal to the right endpoints of the subintervals. Compare $R_{10}$ and $R_{100}$, that is, the sums corresponding to $n = 10$ and $n = 100$: $R_{10} < R_{100}$ $R_{10} = R_{100}$ $R_{10} > R_{100}$ Nothing can be said

F$_3$NH$_3$, B$_2$H$_6$, NaCl, CaCl$_2$, KBr, and Ca$_3$(PO$_4$)$_2$. The answer must be in the form of a complete sentence (not just one word) and identify the type of bonding that is present. If more than one type of bonding is present, all types of bonding must be identified and the description must identify where which type of bonding occurs. Compound 5 Type of bonding Present a) N$_2$ b) O$_2$ c) HCl d) H$_2$O e) NH$_3$ f) SO$_2$ g) BeCl$_2$ h) BF$_3$NH$_3$ i) B$_2$H$_6$ j) NaCl k) KBr l) Ca$_3$(PO$_4$)$_2$
