An open flat belt is to transmit 8 kW. The small pulley has a diameter of 175 mm and rotates at
810 r/min, whilst the large pulley runs at approximately 250 r/min. Both pulleys have a width
of 110 mm. The centre distance between the pulleys is 800 mm. Assume a factor of safety of
eight (8) and an ultimate tensile stress for the flat belt material of 20 MPa. Assume µ = 0.35.
2.1 Specify a belt; i.e. the width, thickness, length and grade
2.2 Calculate a suitable initial tension.
In a class 100 students how much minimum number of students is there whose first name begin with the same alphabet
Write the definition for a class called Distance that has data member feet as integer and inches as float. The class has the following member functions:
void set(int, float) to give value to object
void disp() to display distance in feet and inches
Distance add(Distance) to sum two distances & return distance
1. Write the definitions for each of the above member functions.
2. Write main function to create three Distance objects. Set the value in two objects and call add() to calculate sum and assign it in third object. Display all distances.
If the demand and supply functions in a competitive market are (5marks) Qd = 50 − 0.2P Qs = −10 + 0.3P and the rate of adjustment of price when the market is out of equilibrium is dP /dt = 0.4(Qd − Qs) derive and solve the relevant difference equation to get a function for P in terms of t given that price is 100 in time period 0. Comment on the stability of this market.

A machine producing hair pins produces 1 defective out of 400 on an average. If 100 hairpins are packed in each box.
In above problem, suppose the manufacturer gives guarantee that there will be less than 3 defectives in a box of 100. What is the probability that a box selected at random will meet the guarantee.
you are given a 3x3 matrix of positive integers.You have to determine whether some row is a positive interger multiple of another. If row i is an interger multiple of row j then you have to output p#q where p is the minimum of (i,j) and q is the maximum of (i,j). If there are multiple possibilities for i and j, you have to print for smallest i and the smallest j. Otherwise, you have to output 0#0
