+// SAMPLE PROBLEM 3/8

+clc;clear;funcprot(0);

+// Given data

+m=1500;// The mass of the car in kg

+v_A=100;// The velocity in km/h

+v_C=50;// The velocity in km/h

+rho_A=400;// The radius of curvature in m

+rho_C=80;// The radius of curvature in m

+delta_s=200;// m

+

+// Calculation

+a_t=abs((((v_C/3.6)^2)-((v_A/3.6)^2))/(2*delta_s));// The tangential acceleration in m/s^2

+a_na=((v_A/3.6)^2)/rho_A;// The normal components of acceleration at A in m/s^2

+a_nb=0;// The normal components of acceleration at B in m/s^2

+a_nc=((v_C/3.6)^2)/rho_C;// The normal components of acceleration at C in m/s^2

+F_t=m*a_t;// N

+F_na=m*a_na;// N

+F_nb=m*a_nb;// N

+F_nc=m*a_nc;// N

+F_a=sqrt(F_na^2+F_t^2);// The total horizontal force acting on the tires at A in N

+F_b=sqrt(F_nb^2+F_t^2);// The total horizontal force acting on the tires at B in N

+F_c=sqrt(F_nc^2+F_t^2);// The total horizontal force acting on the tires at C in N
