The base of an aluminum block, which is fixed in place, measures 90 cm by 90 cm, and the height of the block is 60 cm. A force, applied to the upper face and parallel to it, produces a shear strain of 0.0060. The shear modulus of aluminum is 3.0 × 10¹⁰ Pa. What is the sheer stress on the block? A) 180 × 106 N/m² B) 360 × 106 N/m² C) 600 × 106 N/m² D) 720 × 106 N/m² E) 900 × 106 N/m²

Shear stress is given by the product of shear modulus and shear strain. So, shear stress = (3.0 × 10^10 Pa) × (0.0060) = 180 × 10^6 N/m^2.
