The truss is subjected to the system of forces as shown in the following figure. The truss is supported by a pin at A and a pin at E. If P1 = P2 = 4 kN, the force in member (CB) is equal to. 30 30 C 3 m 3 m P1 P2 Select one: a. 4.618 kN - Tension O b. 8 kN - Compression O c. 8 kN - Tension d. 2 kN - Tension

Item 22 A uniform ladder of mass m and length l, leans at an angle against a wall, see the figure. (Figure 1) The coefficients of static friction between ladder-ground and ladder-wall are μc and μw, respectively. The ladder will be on the verge of slipping when both the static friction forces due to the ground and due to the wall take on their maximum values. Figure HG l mg "w 1 of 1 Part B emin = Submit "Leaning ladder problems" are often analyzed under the seemingly unrealistic assumption that the wall is frictionless. You wish to investigate the magnitude of error introduced by modeling the wall as frictionless, if in reality it is frictional. Using the relation found in part A, calculate the true value of min for a frictional wall, taking uc = μw = 0.50. Express your answer to two significant figures and include the appropriate units. Part C Omin = Submit μA Part D Value Request Answer Determine the approximate value of min for the "frictionless wall" model by taking μ = 0.50 and…
