Question

C1-2. High-heel shoes can often do damage to soft wood or linoleum floors. Using a reasonable weight and dimensions for the heel of a regular shoe and a high-heel shoe, determine the bearing stress under each heel if the weight is transferred down only to the heel of one shoe. C1-2

Answer 1

Consider the weight of the women to be 175 lb. P=175 lb Show the free-body of the high-heeled shoes with suitable dimensions as in Figure (1). el 0.3 in. 10.1 in Calculate the area of the high-heeled shoe. Ves (0.3 in.)* +(0.6 in.)(0.1 in.) =0.2014 in. Calculate the bearing stress under the high-heeled shoe. P 175 lb 0.2014 in. 869 psi

Show the free-body of the flat-heeled shoes with suitable dimensions as in Figure (2). 1.2 in. I 0.5 in Calculate the area of the flat-heeled shoe. 4,2 = (1.2 in.) +(2.4 in.)(0.5 in.) = 3.462 in. Calculate the bearing stress under the flat-heeled shoe. P ofat 175 lb 3.462 in. 50.5 psi
