Transcribed Image Text:

Your company wants to produce a baby stroller with a snap-fit cap as in the attached picture to retain the wheels. The desired material is ABS with a flex modulus of 2280 MPa. The cap is 60 mm in diameter and has walls 2.5 mm wide. There are two retaining snaps that are curved (crowned) cantilever beams with constant cross section which are 50 mm long and 40 mm wide and are curved to match the cap's outer diameter. The snaps must deflect 6.24 mm to engage. The lead in angle is 30 degrees and the coefficient of friction, μ, is 0.5. How much force deflection force will the snaps retain and how much will be required to push it on? Report the value in pounds. Note for stiffness factor h=6.24 mm, extrapolate the appropriate curve.
