Two portions of member AB are glued together along a plane forming an angle with the horizontal. Knowing that the ultimate stress for the glued joint is 2.55 ksi in tension and 1.35 ksi in shear, determine the range of values of 0 for which the factor of safety of the members is at least 3.0. B A 2.4 kips 2.0 in.

The cutter shown is used to cut and trim printed circuit sheets. For the position shown, determine the vertical component of the shear force exerted at E. Knowing that a = 33 mm, b = 9 mm, c = 94 mm, L = 219 mm, alpha α = 32 °, β = 48 °, P = 291 N.

An annular washer distributes the load P applied to a steel rod to a timber support. The rod's diameter is 22 mm, and the washer's inner diameter is 25 mm, which is larger than the hole's permissible outer diameter. Knowing that the axial normal stress in the steel rod is 35 MPa and the average bearing stress between the washer and the timber must not exceed 5 MPa, examine the smallest allowed outer diameter, d, of the washer. %3D %3D +22 mm P Figure 4

1.14 Two hydraulic cylinders are used to control the position of the robotic arm ABC. Knowing that the control rods attached at A and D each have a 20-mm diameter and happen to be parallel in the position shown, determine the average normal stress in (a) member AE, (b) member DG. 400 mm E -300 mm- A F 150 mm 150 mm 200 mm B 600 mm- 800 N C
