The ladder of the fire truck rotates around the z axis with an angular velocity of w₁ = 0.20 rad/s, which is increasing at 0.16 rad/s². At the same instant it is rotating upwards at w₂ = 0.61 rad/s while increasing at 0.43 rad/s².

Provide (a) a drawing showing the punch dimensions; (b) a drawing showing the die dimensions; (c) the blanking force necessary. Note: you will need to translate tensile strength to shear based on the conversion from the text and use material properties from the text as well, tensile strength of 405 can be found in Ch. 6 (Metals).
