engineering recuitment UKPSC Polytechnic Lecturer Mock Test 2024 Strength of Materials Springs Closed Coil Helical Spring Under Axial Pull
Two helical springs of stiffness k1 = 50 N/mm and k2 = 100 N/mm are connected in series and parallel combinations as shown in figure, if the system of springs is loaded with 50 kgf load then the resultant deflection of springs in parallel and series combination respectively is: (assume āgā = 10 m/s2)
1
3.33 mm and 15 mm
2
5.5 mm and 12 mm
3
15 mm and 3.33 mm
4
12 mm and 5.5 mm
