In the article “Influence of Crack Width on Shear Behaviour of SIFCON, the maximum shear stress ? of a cracked concrete member is given to be 
, where 
is the maximum shear stress for a crack width of zero, w is the crack width in mm, and k is a constant estimated from experimental data. Assume 
. Given that =50 MPa and w=1.0 mm, both with negligible uncertainty, estimate ? and find the uncertainty in the estimate.
