Determine kinetic friction
WebCivil Engineering questions and answers. The 230−kg crate rests on the ground for which the coefficients of static and kinetic friction are μt=0.5 and μt=04, respectively. The winch delivers a horizontal Determine 1 towing force T to its cable at A which varies as shown in force need the graph. Originally the tension in the cable is zero. Webμ = coefficient of friction. N = normal force, in newtons. Friction can be described as the coefficient of friction multiplied by the normal force. The Friction Calculator uses the formula f = μN, or friction f is equal to the coefficient of friction μ times the normal force N. Note that the standard units for the friction equation is newtons.
