A common method to keep linoleum bathroom floors warm during the winter is to install a flat strip heater with negligible thickness between the linoleum and subfloor, as indicated in the figure below. The figure shows the components of a composite floor, dimensions, properties of each material, and the temperature and heat transfer coefficients on the top (bathroom) and bottom (basement) sides of the composite floor. Given the dimensions of the floor, there are a total of eight studs and eight insulation-filled spaces in the floor (only two are drawn below).    Draw the thermal resistance network equivalent of the problem shown. Indicate the heat input node with an arrow. Calculate all the thermal resistances in your circuit. If the temperature of the linoleum floor must be 20°C (for comfort), what should be the heater’s temperature? Calculate the heater’s power input needed for comfort. Calculate the heat loss to the basement, and propose a solution to reduce it.

A patient is referred to outpatient physical therapy for gait training. During the initial examination, you note that the patient has a left plantarflexion contracture (-5 degrees from neutral). Which of the following compensatory gait patterns would you MOST likely observe at the initial swing phase of their gait cycle?
