Explanation:
Draw a FBD of the beam with reactions at A & B. A is a pin, B is a roller. Try to guess intuitively which way the vertical components of A & B are pointing. Do not show the 6 kN forces in your FBD. Only show the couple moment, or pure moment
Answer:
kindly check the drawing of the FBD of the beam with reactions at A & B. A is a pin, B is a roller in the attached picture.
Explanation:
Without further ado, let's dive straight into the solution to the question above. From the diagram of the FBD of the beam with reactions at A & B it can be shown that the reaction moment is anticlockwise while the moment is clockwise.
The system is at equilibrium and the it does not matter where you place the couple (pure) moment.
The distance from A to C can either be equal or not. If AY = 2.15 kN and M = 25.8. Then, the distance between A and B = 25.8/2.15 = 12m.
Consider a single crystal of some hypothetical metal that has an FCC crystal structure and is oriented such that a tensile stress is applied along a[102] direction. If slip occurs on a( 111) plane and in a [ 101] direction, compute the stress at which the crystal yields if its critical resolved shear stress is 12.76 MPa.
a. 13.96 MPa
b. 52.1 MPa
c. 0 MPa
d. 30.9 MPa
e. 3.1 MPa
2 Describe the four major disciplines of engineering and identify problems or projects that an engineer in each discipline might encounter. Chemical engineering Civil engineering . Electrical engineering Mechanical engineering
Answer:
Chemical engineering
Uses chemical processes to find new ways to produce goods. Making antibiotics, pesticides, safe clothes, and foods.
· Civil engineering
Builds structures to try and make them efficient. Makes a tornado-proof house, explosion-proof bunker, or easily navigable subway system.

NICE
Explanation:
Rigid bar ACB is supported by an elastic cir-cular strut DC having an outer diameter of 15 in. and inner diameter of 14.4 in. The strut is made of steel with a modulus elasticity of load P 5kips5 E 5 29,000 ksi. Point is applied at B. Calculate the change in length of the circular strut DC. What is the vertical displacement of the rigid bar at point B
Answer:
The change in length of the circular strut DC = 0.0028 in.
The vertical displacement of the rigid bar at point B = 0.00378 in.
Explanation:
We have the following parameters or information in the question given above:
=> The outer diameter = 15 in., the inner diameter = 14.4 in., the modulus elasticity of E = 29,000 ksi, and the Point load P = 5kips.
The diagram showing the rigid bar ACB is supported by an elastic cir-cular strut DC is given in the attached picture below.
According to Newton's law of motion, it can be seen that the force on CD, that is FCD is equal and opposite to ACD. Hence, FCD = ACD.
Where FCD = p × [4 + 5] ÷ [sin Ф × 4].
kindly note that from the diagram sin Ф = 3/5, cos Ф = 4/5 and tan Ф = 3/4. Also p =5.
Hence, FCD =[ 5 × 9] ÷ [3/5 × 4] = 18.75 kip. So FCD = ACD.
The next thing here is to determine the area and length of CD, say the area of CD is G, thus, G = π/4 × [ 15² - 14.4²] = 13.854 in².
The lenght of CD is = √[4² + 3²] = √[16 + 9] = 5ft. Thus, 5 × 12 = 60in.
Hence, the change in length of the circular strut DC = [18.75 × 60] ÷ 13.854 × 29000 = 0.0028 in.
The vertical deflection of CD = 0.0028 × 3/5 = 0.00168 in.
We have that; 4 /CV = 9BV. Hence, BV = 9/4× CV.
(CV = vertical deflection of CD).
The vertical displacement of the rigid bar at point B = 9/ 4 × 0.00168 in = 0.00378 in.
