Carrying household appliances can be very difficult due to the weight and size. Some movers place the appliance on a dolly and move it around, however this can cause damage to floors, and it also does not work on stairs. A new technique is to utilize moving straps.

When using these straps, a horizontal force is typically applied to the top of the appliance. Why?
