At a mail sorting facility, packages slide down a ramp but are stopped part way down the ramp so that they can be scanned. While the packages are scanned, they are held in place by a horizontal, spring-loaded arm. Calculate the force that must be applied by this arm to hold a package on the ramp. The ramp is at an angle of 31.5° with the horizontal. The package has a mass of 4.75 kg. The coefficient of static friction between the ramp and the package is 0.455.
