1 5. Consider a thin cantilever loaded as shown in Fig. P5. Assume that the bending Mzy stress is given by Ox=- = -2x2y and o; = Txy Tyz = 0. What will be the stress componeent in terms of x and y? (a) Oy = 2 (3hºy – y2 – 2h3), (b) oy = 8 (3h²y – y3 – 2h3), (c) 0y = (3h2y – y3 – 2h²), (d) Oy (3hy – y3 – 2h3), (e) none of above...
6. Two thin-walled circular tubes, one having a seamless section, the other a split section as shown in Fig. P6, are subjected to the action of identical twiisting moments. Both tubes have equal outer diameters do, inner diameter di, and thickness t. What will be the ratio of the angles of twist bewteen the seamless tube, 0,, and that of split tube, 8z, i.e., the value of ? (a)). (b)) (c)(h), (d) }). (e) none of above 02 May =-...
The cross section of the cantilever beam loaded as shown in
Fig. 8-20 is rectangular, 50 × 75 mm. The bar, 1 m long, is
aluminum for which E = 65 GPa. Determine the permissible maximum
intensity of loading if the maximum deflection is not to exceed 5
mm and the maximum stress is not to exceed 50 MPa.
Ans. w0 = 14.1 kN/m and 17.1 kN/m. Select 14.1 kN/m.
