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.
you are given a secret string and you are given a guess is string. both staying have exactly 5 characters. assume that each letters occurs at most one time in the secret string and guess string. some of the letters in the gas is string occurs in the same position as the secret string. call the number of such letters as i. some other letters in the guess string occurs in the secret but in some other position. call the number of such latter as j. you have to output (#)
In a class 100 students how much minimum number of students is there whose first name begin with the same alphabet
Green bell is a retail gaint in India. Currently only confined to metro cities for their giant super store outlets, they are planning to spread to smaller cities in India. While working on the resources allocation, HR Is planning on shifting a few of the current staff to new location while recuruting local staff at each location in parallel. They need to engage the current staff in training for the newer audience. Discuss the expansion from the point of view of hofstede's five dimension to include in the training.
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.
