**Title: Understanding the Physics of Superhuman Strength**

Comic-book superheroes are sometimes able to punch holes through steel walls. 

(a) If the ultimate shear strength of steel is taken to be \(2.50 \times 10^9 \, \text{Pa}\), what force is required to punch through a steel plate 2.30 cm thick? Assume the superhero’s fist has a cross-sectional area of \(9.0 \times 10^{-2} \, \text{m}^2\) and is approximately circular.

(b) Qualitatively, what would happen to the superhero on delivery of the punch? What physical law applies?
