In Java In designing a building, structural engineers must determine whether each of thebuilding’s support columns is thick enough to support the column’s expected load.Assume the column is wooden and has a solid square cross section. To be safe, allthree of these conditions must be met:• The column should not be too slender, that is:height / width ≤ 50, where 50 is a special value called the slendernesslimit.• To prevent the column from buckling, make sure this requirement ismet:expected load ≤ (0.3*E*area) / (height/width)2,where E = 1,700,000 psi is a special value called the modulus ofelasticity.• To prevent the column from compressing, make sure this requirementis met:expected load ≤ area * stress,where stress = 1450 psi = maximum allowable stress parallel to thegrain.Write a program that determines whether a wooden column with a given height isthick enough to support a given expected load. More specifically, read in height,width, and expected load values and then print, “The…

Using Java code an elevator simulator that uses polymorphism and object-oriented programming tosimulate the movement of elevators in a building with multiple types of passengers and elevators.The system has 8 elevators, each of which can be one of 4 types of elevators, with a certainpercentage of requests for each type. Similarly, each passenger can be one of 4 types, with adifferent percentage of requests for each type. There are 4 types of passengers in the system:Standard: This is the most common type of passenger and has a request percentage of 70%.Standard passengers have no special requirements.VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priorityand are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have largeitems that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request percentage…
Q1: Research Groups In response to popular demand, Dan’s established two research groups A and B composed of his n graduate students. Each of these students is a member of exactly one of the two groups at any given time. The students are numbered from 1 to n in some arbitrary order. To measure the success of his research groups, Dan assigns a citation score to each of them. Initially, both groups have citation score 0. Throughout the semester, events of the following two types happen: Student x publishes a paper in which they cite student y’s work (youcan assume all of the students have been around long enough to have prior research that can be cited). As a result, If x and y are in the same group, their group’s citation score increases by 1. If x and y are in different groups, y’s group’s citation score increases by 5. Dan changes student x’s group (from A to B or from B to A) to have them work on different projects. To assess the overall success of the research groups, Dan…
