need answer asap please thank you The figure 2 shows a cantilever truss connected to a weight of 50 kN at it end E. The trussis connected via a pin at A and a roller at I. Determine:(a) Draw the free body diagram of the truss (FBD).(b) Determine the reactions at pin A and the roller I.(c) Find the force in members IB and IH using the method of joints. Indicate if eachmember is in tension or compression. "N.B. a solution by the method of sections willget a mark of zero (0)".(d) Find the force in members CD, GD, and GF using the method of sections. Specifyin each case whether the member is in tension or compression. "N.B. a solution bythe method of joints will get a mark of zero (0)".3 mABD3 mH3 m3 mF3 mFigure 2E

When using a pencil eraser, you exert a vertical force of 6.00N at a distance of 2.00cm from the hardwood-eraser joint. The pencil is 6.00mm in diameter and is held at an angle of 20.0 to the horizontal. (a) By how much does the wood flex perpendicular to its length? (b) How much is it compressed lengthwise?
Hanging from the ceiling over a baby bed, well out of baby’s reach, is a string with plastic shapes, as shown here. The string is taut (there is no slack), as shown by the straight segments. Each plastic shape has the same mass m , and they are equally spaced by a distance d , as shown. The angles labeled describe the angle formed by the end of the string and the ceiling at each end. The center length of sting is horizontal. The remaining two segments each form an angle with the horizontal, labeled . Let T1 be the tension in the leftmost section of the string, T2 , be the tension in the section adjacent to it, and T3 be the tension in the horizontal segment. (a) Find an equation for the tension in each section of the string in terms of the variables m,g , and . (b) Find the angle in terms of the angle .
