Problem 3 A ladder supports the 80-kg man in the position as shown in Fig. 3. The surface is rather slippery, where the coefficient of static friction at A and B is μs = 0.25. Fortunately, an invisible guy helps hold the ladder BC, providing a couple moment shown in the figure. (a) Draw the free body diagram of AC and BC, respectively. (b) Determine the greatest angle 0 so that the ladder does not slip under this condition. Start by assuming the ladder slips at A. 0.25 m 2.5 m 2.5 m OOOO 100 N·m Fig. 3 B

Q4(2). The beam is pin-supported at A, and supported by a roller at B. The lengths are ₁ = 1.7 m and 2 = 4.0 m. The cross section is a solid rectangle as shown in the image with h= 180 mm. It is subjected to a uniformly distributed load with load intensity w= = 36 kN/m. If the location of point Cis indicated on the cross section, and its state of stress can be represented on the volume element as shown, determine the shear stress Txy (in the unit of MPa). Negative sign must be included if the direction is opposite to what's shown in the state of stress image. 50 mm 50 mm 1 Fay -4- "110 Ox 1.5 m 2 m- 2.5 m B Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point.

2. The figure shows a jam cleat designed for a sailboat where the large friction forces developed by the cams prevent the rope from slipping. Determine the force R supported by each cam bearing from the 900-N rope tension. The coefficient of static friction between the rope and the cams is 0.8. Hint: FBD of one cam only. The line of action of R passes through the point directly above the center of the 80-mm circular cam profile and the center of the cam mounting pin. Ans: R = 1885 N 80 mm. 20 mm 900 N

A tapered cantilever beam AB supports a concentratedload P at the free end (see figure). The crosssections of the beam are rectangular with constantwidth b, depth dA at support A, and depth dB = 3dA/2 at the support. Thus, the depth d and moment of inertiaI at distance x from the free end are, respectively, d = (dA/2L)(2L+x) I=(bd3/12) =(bd3A/96L3)(2L+x)3 = (IA/8L3)(2L+x)3in which IA is the moment of inertia at end A of thebeam.Determine the equation of the deflection curveand the deflection δA at the free end of the beam dueto the load P.
