+//To find power absorbed
+clc
+//Given:
+d1=400,r1=d1/2,d2=250,r2=d2/2 //mm
+p=0.35 //N/mm^2
+mu=0.05
+N=105 //rpm
+W=150*1000 //N
+//Solution:
+//Calculating the angular speed of the shaft
+omega=2*%pi*N/60 //rad/s
+//Calculating the total frictional torque transmitted for uniform pressure
+T=2/3*mu*W*(r1^3-r2^3)/(r1^2-r2^2)/1000 //N-m
+//Calculating the power absorbed
+P=T*omega/1000 //kW
+//Calculating the number of collars required
+n=W/(p*%pi*(r1^2-r2^2))
+//Results:
+printf("\n\n Power absorbed, P = %.2f kW.\n",P)
+printf(" Number of collars required, n = %d.\n\n",n+1)
