Chapter 3, Problem 17E

Q: For the spring system shown in the accompanying figure, determine the displacement of each node. Start by identifying the size of the global matrix. Write down elemental stiffness matrices, and show the position of each elemental matrix in the global matrix. Apply the boundary conditions and loads. Solve the set of linear equations. Also, compute the reaction forces. k2 = 9 lb k1 = 20b in 20 lb k,=5 lb ww lb in kz = 5 lb in ks = 9 in lb k6 = 9 in 50 lb k4 = 20 lb kg = 20 b in in

the previous answer i got from this website was wrong, part A must be an integer or decimal part B Xa and Xc are = 0

hi can you please answer question "problem 5-4"? please see image attached thank you

A propped cantilever beam is loaded by a bending moment of the magnitude M_B at the point B as shown in Figure Q1. The cross-section of the beam is a rectangle of the width w and the hight ℎ that are constant along the length of the beam L. The beam material’s Young’s modulus is Q. Assuming the positive deflections and positive vertical reaction forces are upward,  calculate the value of the reaction forces at points A and B   the absolute value of the reaction bending moment at point A   A) Let R represent the reaction force at Support B. By releasing the beam at Support B and imposing a force R at Point B, the deflection of the beam consists of two parts,i.e. Part I- the deflection caused by M_B ; Part II- the deflection caused by R Please treat R, w, h , L , E  as variables in this step , the mathematical equation for the deflection at Point B caused by R ( Part II) can be written as:   b)  Using the provided data: cross-section width w = 14  mm, cross-section hight h = 82…

In Figure Q3a, a beam is supported at A and C with a uniformly distributed load of20 kN/m between A and B. Draw and label the shear force diagram (SFD) andbending moment diagram (BMD) for the beam shown in Figure Q3a. Label thevalues for shear force and bending moment at points A, B, C & at the beam midpoint M; the maximum bending moment and its distance from A; and clearlyindicate the type of bending between AB and between BC

What is the magnitude of the reaction force at RAX and RAY in Newtons What is the magnitude of the reaction force, RBX and RBY in Newtons.
