Shear Modulus: The base of a metal 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 this metal is 3.0 × 1010 Pa. The shear stress on the block in megapascals is closest to
A. 180 MPa.
B. 360 MPa.
C. 600 MPa.
D. 720 MPa.
E. 900 MPa.
