WRAP-Iowa Ramp Design Aid app analytics for January 6

This app provides suggested measurements for stairs rise and run as well as for the suggested cut angle for wheelchair ramp stringers. In the Calculate Riser Heights screen, the user can enter a single height value to have the app calculate all of the required measurements to cut the stringer rise and run to build stairs. If the user has a specific number of risers, there is an over-ride that will calculate all values given the entered number of risers. In the Calculate Stringer Cut Angle screen, the user can enter an overall height between the two ends of the stringer as well as the length of the stringer and the app will calculate the angle at which the ends of the stringer must be cut.. The app also includes links to the WRAP Iowa website and to an excellent article on stair construction on the Fine Woodworking website.
