School-Books On Tape: The Tensile And Adhesive Strength Of Duct Tape In A College Backpack, Robin Elizabeth Ker Apr 2015

School-Books On Tape: The Tensile And Adhesive Strength Of Duct Tape In A College Backpack, Robin Elizabeth Ker

Honors Theses

Two categories were used to assess the strength of duct tape constructions: adhesive strength and tensile strength. Previously made duct tape backpacks frequently suffered from adhesive failure around shoulder straps. When a backpack is lifted, it experiences a force which is greater than the resting weight. The hypothesis states that there is an area of application between two pieces of duct tape such that they will behave as a uniform piece and experience tensile failure, that two sufficiently overlapped pieces can hold within 5% of the load carried by a single piece, and that there is a relationship between the …


Multi-Segment Foot Joint Kinematics With Varying Midfoot Orthotic Postings, Hilary F. Feskanin Apr 2015

Multi-Segment Foot Joint Kinematics With Varying Midfoot Orthotic Postings, Hilary F. Feskanin

Honors Theses

Foot orthoses are often prescribed to prevent and treat lower limb disorders. While the success of these devices is well documented, the mechanisms behind them are unclear. Due to methodological limitations, many studies have focused on the rearfoot. This is the first study to assess the effects of midfoot-targeted orthotic strategies on midfoot and rearfoot kinematics. Gait mechanics were recorded for 19 healthy females walking in four orthotic conditions: valgus midfoot post, varus midfoot post, heel lift and standard/control. The midtarsal and ankle joint 3D kinematics for the three experimental conditions were compared to the control condition. Variables of interest …
