Simple supports or knife edge supports Roller support Smooth surface support Fixed or built in support 2. A beam supported on the knife edges A and B is shown in Fig.
Define and explain the terms. Principle of equilibrium, force law of equilibrium and moment law of equilibrium. A number of forces are acting on a body. What are conditions of equilibrium, so that the body is in equilibrium?
Two forces are acting on a body and the body is in equilibrium. What conditions should be fulfilled by these two forces?
How will you prove that a body will not be in equilibrium when the body is subjected to forces which are equal and opposite but are parallel?
Three concurrent forces are acting on a body which is in equilibrium, then the resultant of the two forces should be equal and opposite to the third force. What do you mean by action and reaction? Explain and define the term: Draw the free-body diagram of a ball of weight W, placed on a horizontal surface.
What is the difference between a roller support and a hinged support? What are the important types of loading on a beam? Differentiate between uniformly distributed load and uniformly varying load on a beam. Name the different methods of finding the reactions at the two supports of a beam.
How will you find the reactions RA and RB by analytical method. Describe in details the different steps involved in finding the reactions of a beam by graphical method.
Define and explain an overhanging beam. What is the main advantage of roller support in case of the steel trusses of the bridges? Define and explain the terms: Perfect frame, imperfect frame, deficient frame and a redundant frame.
State the difference between a perfect frame and an imperfect frame.
What are the different methods of analysing or finding out the forces a perfect frame? Which one is used where and why? How will you use method of section in finding forces in the members of a truss? How will you find the forces in the members of a joint by graphical method?
What are the advantages or disadvantages of graphical method over method of joints and method of section?
What is the procedure of drawing a vector diagram for a frame? How will you find the reactions of a cantilever by graphical method? What are the assumptions made in the analysis of a simple truss. B Numerical Problems 1. Three forces F1, F2 and F3 are acting on a body as shown in Fig.
Determine the magnitude and direction of the force P. Three parallel forces F1, F2 and F3 are acting on a body as shown in Fig. Three forces of magnitude 40 kN, 15 kN and 20 kN are acting at a point O. Determine the magnitude and direction of the resultant force.
A lamp weighing 10 N is suspended from the ceiling by a chain. Draw the free-body diagram of a ball of weight W supported by a string AB and resting on a smooth horizontal surface at C when a horizontal force is applied to the ball as shown in Fig.
A smooth circular cylinder of weight N and radius 10 cm rests in a right-angled groove whose sides are inclined at an angle of and to the horizontal as shown in Fig.Unformatted text preview: Bio - Macromolecules Post-Lab Assignment Name: Lab Section: Date: Group Members: Ariel Arizmendi 0AB ### Complete all tables and questions on the 5 tabs following this Title grupobittia.coms to the questions must be written in complete sentances.
