Question

udering the distributed load below, answer questions 4 and 5 16. The support at A is: 17. The reactions at A are a Roller a. A,A 10kN and MA-31.3 RN.m b. Pin. b A, -10N A, 104N and M,-313 k.N.m c Fixed. d. Distributed The rod shown has a length L ‘ 4 ft, and is pinned at its attached spring has a stiffness &-50 ib/ftand an unstretched length Le 2 t. The spring is unstretched wihen 9- B. The stretched length /when 6-4S"is: 257 45', the force in the spring is: 19 When θ b. 295h 1.85 f d. 3.65 ft 20 1f a force F actinf at point p is represented by a force ( F M, the systems are equivalent if B M the moment of F, about P c M- the moment of F, about another point Q

Answer 1

Semantic Network distributed LOAD h. represented by y-3(1-x 2/295) exerts C-total FORCE d. at CENTROID (X, Y) h. having amount of UNITS (Ft) athematically 2 5 ダ 25 L 3 2 5

support A h. of BEAM h. having distributed LOAD y-3(1-x^2/25) h. exerting total FORCE (Ft) exerts CFORCE d. in X-DIRECTION h. having *amount of UNITS (Ax) athematically d. in -DIRECTION h. having *amount of UNITS (Ay) athematically causing ROTATION o. about h. having amount of UNITS (Ma) athematically

The support at A is fixed
