(a) Two parallel fillet welds

(b) Two transverse fillet welds.

3) Draw a Knukle joint to transmit the load of 120 KN in tension or compression. Suppose the following allowable stresses.

Sketch tensile stress = 90 N/mm2.
Sketch Shear stress = 70 N/mm2.
Sketch compressive stress = 160 N/mm2.

4) Sketch a C.I. piston for single acting four stroke engine for Specifications given below.

Cylinder bore = 120 mm
Stroke = 1410 mm
