Asap 1. The bracket is made of steel (Young's modulus 200 GPa; Poisson's ratio 0.3). When the force P is applied to the bracket, the gages in the strain rosette at point A have the following readings: E.-60 μ . Ep 135 μ l, and E.-264 μ (a) Determine the shear strain at point A. (b) Determine the orientation of the principal plane, the in-plane principal strains, the maximum in-plane shear strain, and the average in-plane normal strain. Determine the...
Two forces P and Q are applied as shown at point A of a hook support knowing that P = 15N and Q = 25N, determine graphically the magnitude and direction of theirresultant using (a) parallelogram law, (b) Triangular law of addition of vectors?
The rigid bar ABC is supported by a pin at point A and by two wires attached at B and C as shown in the figure. If the applied point load P produces a clockwise rotation of the rigid bar ABC of 5°, find the normal strain for both wires. All dimensions in mm.
Two forces P and Q are applied to the lid of a storage bin as shown, where P = 48 N, Q = 78 N. Answer part a. before answering part b. Using trigonometry, determine the direction of the resultant of the two forces. (Round the final answer to a single decimal place. result should be an acute angle measured from a horizontal axis.) The direction of the resultant of the two forces is _______ °.
Please answer in numerical order. 1. Use ρ-p0.004 and choose (you decide) the number (3 to 5) and size of steel bars from the attached table. Then proceed to determine (a) the size of the cross-sectional area, (b) the moment capacity of the RC section that you design, and (c) show where is the neutral axis on the diagram (or sketch a new one). 2.5" Given: fe 3,000 psi, fy -60,000 psi Concrete cracking strain 0.003 Initial yielding strain of...
As shown, two composite columns of steel and concrete are used to support a rigid platform. The columns are cylindrical, with a steel bar encased in concrete. The outer diameter of each column is dc = 24 cm. The steel in the left column has a diameter of dı = 18 cm. A load of P = 52 kN is applied with L1 = 1.5 m and L2 = 2.2 m. The height of the columns is h = 2.6...
3. A two bar truss structure is shown in Figure 1. The coordinates of Points A, C and B are given by (0,0), (0, 10") and (10",0), respectively, in which the x-axis is from A to B and the y-axis is from A to C. Points A and C are fixed. The cross-sectional area of all members in inch?. A vertical point load, P, is applied at the tip of the structure, Point B. Based upon either the Principle of...
A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
