I. Conceptual Question: Select the ONE best choice for the following questions. I.) In a multiforce member, the member is generally subjected to an internal: (a) Normal force, (b) Shear force, (c) Bending moment, (d) All of the above, (e) none of the above. (2 A column is loaded with a vertical 100 N force. At which sections are the internal loads the same? (a) P Q, and R, (b) P and Q, (c) Q and R, (d) None of the above. (e) 100 N (3.) A column is loaded with a horizontal 100 N force. At which section are the internal loads the lowest? (a) P, (b) Q. (c)R, (d) S, (e) none of the above. 100 N (4.) If a block is stationary, then the friction force acting on it is: (a) HsN, (b)-HsN, (c)2HsN, (d)=, (e) none of the above. 5.) The ladder AB is positioned as shown. What is the direction of the friction force on the ladder at B? (a) (b).. (c)-, (d)1. (e) .Explanation / Answer
1)(d)All of the above
Its subjected to Normal, Shear and Bending moments
2)(c)Q and R
3)(d)S
since its farthest point
4)(b)us N
since its stationary static frictioanl force is acting.
5)(d)^
The frictional force at B will ne directed upwards indicated by option (d)
