Question

Physics: A block of gelatin is 120mm by 120mm by 40mm when unstressed. A force of 49N is applies tangentically to the upper surface causing a 10mm displacement relative to the lower surface. the block is placed such that 120 × 120 comes out of both the lower and upper surface. Find the shearing stress, shearing strain and shear modulus.​

You can solve this problem by dimensional analysis, that is by merely cancelling out the units until you reach the units of the unknown measurement. for torque, its unit is n-m or joule. thus,

525n/c * (5 x 10^-6 c) * (0.0012 m) = 3.15 x 10^-6 joules

i hope i was able to . have a good day.
