Accordingly, compute the value of M by formula (10) 

 for 101 and w t at quarter point. 



M = jMs + j / M l - M 2 (10) 



3f for t0i at quarter point . 



M = 34 (2838.75) -f- % (0) - 100 = (in-.). 7 Kip Feet. 



M for i0i at quarter point, 



M = K (3563.75) + % (37.5) - 287.5 = 631.6 Kip feet. 



The latter value, 631.6, is the maximum bending mo- 

 ment at the quarter point. A comparison of this value
