A single riveted lap joint of two similar plates as shown in the figure below has the following geometrical and material details.

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 $σ_p$ = $200$ $MPa$, allowable shear stress of the rivet $σ_s$ = $100$ $MPa$ and allowable bearing stress of the rivet $σ_c$ = $150$ $MPa$.

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

  1. $7.50$
  2. $15.00$
  3. $22.50$
  4. $30.00$

A butt weld joint is developed on steel plates having yield and ultimate tensile strength of $500$ $MPa$ and $700$ $MPa$, respectively. The thickness of the plates is $8$ $mm$ and width is $20$ $mm$. Improper selection of welding parameters caused an undercut of $3$ $mm$ depth along the weld. The maximum transverse tensile load (in $kN$) carrying capacity of the developed weld joint is _______

For spot welding of two steel sheets (base metal) each of $3$ $mm$ thickness, welding current of $10000$ $A$ is applied for $0.2$ $s$. The heat dissipated to the base metal is $1000$ $J$. Assuming that the heat required for melting $1$ $mm^3$ volume of steel is $20$ $J$ and interfacial contact resistance between sheets is $0.0002$ $Ω$, the volume (in $mm^3$) of weld nugget is _______
