Question

Two 12 mm thick plates are joined with single riveted
lap joint. If 22 mm rivets are placed at an interval of 60
mm, then calculate strength, rivet value and efficiency of
220612(20)
[3]
the joint. Power driven shop rivets are used.​

Answer 1

Explanation:

The separation between the plates of a capacitor of capacitance 2uF is 4 mm. Initially, there is air

between the plate's. If two dielectric slabs of area of cross-section same as the capacitor, thickness 2 mm

each, and dielectric constant 3 and 5 respectively are introduced, the capacitance becomes (in 1F):

(A) 4

(B) 7.5

(C)

8

(D) 15
