A Simply Supported Laminated Beam of Length L = 0 $240 \mathrm{~N}$

question 75

Short Answer

A simply supported laminated beam of length L = 0.5 m and square cross section weighs 4.8 N. Three strips are glued together to form
The beam, with the allowable shear stress in the glued joint equal to
0.3 MPa. Considering also the weight of the beam, the maximum load P
That can be applied at L/3 from the left support is approximately: (A) $240 \mathrm{~N}$
(B) $360 \mathrm{~N}$
(C) $434 \mathrm{~N}$
(D) $510 \mathrm{~N}$
