A bracket is attached to a vertical column by means of two identical rivets U and V separated by a distance of 2a = 100 mm, as shown in the figure. The permissible shear stress of the rivet material is 50 MPa. If a load P = 10 kN is applied at an eccentricity e = 3√7 a, the minimum cross-sectional area of each of the rivets to avoid failure is ___________ mm2.







width of the plate $$w = 200$$ $$mm,$$ thickness of the plate $$t = 5$$ $$mm,$$ number of rivets $$n = 3,$$ diameter of the rivet $${d_r} = 10\,\,\,mm,$$ diameter of the rivet hole $${d_h} = 11\,\,\,mm,$$ allowable tensile stress of the plate $${\sigma _p} = 200\,\,MPa,$$ allowable shear stress of the rivet $${\sigma _s} = 100\,\,MPa$$ and allowable bearing stress of the rivet $${\sigma _c} = 150\,\,MPa.$$
If the rivets are to be designed to avoid crushing failure, the maximum permissible load $$P$$ in $$k/N$$ is

If the plates are to be designed to avoid tearing failure, the maximum permissible load $$P$$ in $$kN$$ is


Direct shear stress in $$MPa$$ in the most heavily loaded rivet is

The resultant shear stress on rivet $$P$$ is closest to

The primary and secondary shear loads on rivet $$p,$$ respectively are
