Question

A square aluminium (shear modulus is 25 x 10^9Nm^-2) slab of side 60 cm and thickness 15 cm is subjected to a shearing force (on its narrow face) of 18.0 x 10^4 N. The lower edge is riveted to the floor. The displacement of the upper edge is____μm.

Accepted Answer

Correct answer: 48. (48) FA=η xl⇒ F lA η=x ⇒x= 1 8×1 0^4×6 0×1 0^−26 0×1 0^−2×1 5×1 0^−2×2 5×1 0^9 =4 8×1 0^−6m=4 8 μ m

$A square aluminium (shear modulus is 25 x 1 0^{9} N m^{- 2}) slab of side 60 cm and thickness 15 cm is subjected to a shearing force (on its narrow face) of 18.0 x 1 0^{4} N. The lower edge is riveted to the floor. The displacement of the upper edge is____μ m.$
