Question

Please complete the problem on the following page and include a clearly illustrated (this means NEAT and STRAIGHTFORWARD) solution process. Please focus on the following four (4) areas in your solution process. 1. Problem Understanding State, in your own words, the essential question being asked by the problem. Include a list of known quantities (variables along with numerical values if provided) and a list of the desired unknown quantities 2. Free-Body Diagram-Complete an appropriate FBD for each body of interest as required by the problem. Include all forces and necessary dimensions. Please use a straight edge for all forces and dimension lines and clearly label all points and forces. Your FBD should be drawn to scale. 3. Governing Equations -Write out all governing equations first in symbolic form, and second with numerical substitution. Units do not need to be shown, but the signs of all forces should be in accord with your chosen (or supplied) coordinate system. 4. Answer- Solve the problem for each of the required unknowns and clearly list your answers with a double underline. Units should be included for each answer, and the answer should be written to the correct number of significant figures as outlined by your textbook

Explanation / Answer

let us consider free body of CEF .Let the horizontal force at E be Ex and vertical force be Ey

from moment equilibrium about C,we get

(150*9.8*2)-1.6Ey=0

Ey = 1837.5 N (vertically upwards)

vertical force exerted by CEF on BE at E = 1837.5 N (vertically downwards)

if we consider member BE and consider moment equilibrium of BE at B,we get

1.6Ey+1.6Ex=0

Ex = -Ey=-1837.5 N =1837.5 N(towards left)

Horizontal force exerted on CEF by BE at E = 1837.5N (towards right)

Force at pin C:

(150*9.8)-1837.5=-367.5 N=367.5 N (vertically downwards)

1837.5 N (towards left)

Force at pin B:

vertical force = By=1837.5 N(vertically upwards)

horizontal force = Bx = 1837.5 N(towards right)
