A) Imagine a procedure used for the execution of a certain work, as shown in the following figure. Such a crane has a mass of 1000 kg and is transporting a coffin with a total mass of 2400 kg. Assume that support A is fixed, support B is movable, and point G is the center of gravity of the lift. What are the support responses in kN? Question 1 options: a) The support responses are as follows: Rax = Rbx = 34 kN and Ray = 109.33 kN. b) The supporting responses are as follows: Rax = Ray = 109.33 kN and Rbx = 34 kN. c) The support responses are as follows: Rax = 56.8 kN; Rbx = 109.33 kN and Radius = 34 kN. d) The support responses are as follows: Rax = 156.7 kN; Rbx = 89.65 kN and Radius = 34 kN. e) The supporting responses are as follows: Rax = Rbx = 109.33 kN and Ray = 34 kN.

Question 1 options:
a) The support responses are as follows: Rax = Rbx = 34 kN and Ray = 109.33 kN.
b) The supporting responses are as follows: Rax = Ray = 109.33 kN and Rbx = 34 kN.
c) The support responses are as follows: Rax = 56.8 kN; Rbx = 109.33 kN and Radius = 34 kN.
d) The support responses are as follows: Rax = 156.7 kN; Rbx = 89.65 kN and Radius = 34 kN.
e) The supporting responses are as follows: Rax = Rbx = 109.33 kN and Ray = 34 kN.
B. Consider the beam shown in the following figure. In this beam, there are different types of existing forces, such as applied moment, distributed load and point load. Knowing the magnitude of each of the forces, ask for the vertical support responses at point A and point C.
Question 2 options:
a) The occurrence at point A is 5.75 kN; and the occurrence in C, of 34.25 kN.
b) The occurrence at point A is 14.25 kN; and the occurrence in C, of 34.25 kN.
c) The occurrence at point A is 13.75 kN; and the occurrence in C, of 26.25 kN.
d) The occurrence at point A is 20.75 kN; and the occurrence in C, of 22.50 kN.
e) The occurrence at point A is 5.75 kN; and the occurrence in C, of 21.75 kN.
