Consider a simplified two-joint robotic arm where the two joints are connected by rigid links.Each joint has a mass, and the links are modeled as idealized rods. The motion of each jointaffects the other through the coupling of forces. The system can be modeled by the followingsecond-order coupled ODEs:
m1θ1" + k1(θ1 − θrest) + k3(θ1 − θ2) = 0 (equation 1)m2θ2" + k2(θ2 − θrest) + k3(θ2 − θ1) = 0 (equation 2)
where θ1(t) and θ2(t) represent the angular positions of the first and second joints, respec-tively. m1 and m2 are the effective masses at each joint. k1, k2 and k3 are the stiffnessconstants representing the elastic restoring forces in the joints and links. θrest = 0 representsthe equilibrium position for each joint.The parameters are:m1 = 1, m2 = 1, θrest = 0, k1 = 1, k2 = 2, k3 = 3, θrest = 0The initial conditions are:θ1(0) = 1, θ2(0) = 2Please solve by hand to get θ1(t) and θ2(t) using eigenvectors and eigenvalues. Show all steps/calculations, and provide a written description…

- Sudoku Puzzle Rules Solving a Sudoku puzzle does not require the knowledge of mathematics but it does require logical thinking. A Sudoku puzzle is a grid of nine by nine squares or cells that have been subdivided into nine "regions" of three by three cells. Consider the following diagram: The objective of Sudoku is to enter a digit from 1 through 9 in each cell, in such a way that: Each horizontal row (shown in blue) contains each digit exactly once. Each vertical column (shown in pink) contains each digit exactly once. Each sub grid or region (shown in orange) contains each digit exactly once. In each Sudoku puzzle, some digits have already been entered, you may not change these. Your job is to fill the remaining cells with digits keeping in mind the three rules discussed above. Sudoku puzzles have become so popular that they can be found in newspapers and magazines around the world. If you are ever planning a long trip where you may be stuck in a car, Sudoku can help to pass the…arrow_forward(3) Let G be a group and let gЄ G.

Part 1: In M4LE1 Hand-in Assignment you were to select a vehicle you would like to drive. In this hand-in assignment you are to choose a similar (or same) vehicle and find the cost to lease it. Describe the vehicle by stating make, model, special features, colour, et cetera. Find the price of the vehicle. You may look for the price at a dealer, in a newspaper, on TV, on the Internet, or source of your choice. Be sure to indicate the price and where you found the information. Assume that you have $5000 for a down payment to apply to the lease. Calculate the total cost of leasing the vehicle, including the down payment and applicable taxes. You may want to use a leasing calculator. Be sure to show how you arrived at your answer. Part 2: Compare the cost of buying the vehicle using your information from M4LE1 to the cost of leasing determined in Part 1. Would…arrow_forward
- No chatgpt Asap Upvotearrow_forwardThis problem requires you to apply your skills with fractions and think logically to develop your response. Please show as much work as possible to clearly show the steps you used to find the solution. You must support any results you give with an explanation that makes sense. A wealthy doctor owned 17 expensive cars. Before he died, he prepared a wacky will for his 3 sons. The will stated that his 17 cars be divided among his three sons in a particular way: half of the cars were to go to his eldest son one-third to his middle son one-ninth to his youngest son. Everyone was puzzled. How can 17 cars be divided in such a way? While the sons were arguing about what to do, a mathematics teacher drove up in her new sports car. "Can I be of help?" she asked. After the sons explained the situation, she parked her sports car next to the doctor’s 17 cars and hopped out. "How many cars are there now?" The sons counted 18. Then she carried out the terms of the will. She…arrow_forwardYour task in this assignment is to decide whether owning a vehicle is worth the monthly costs. Follow the steps below to justify your decision: Choose a vehicle that you would be interested in purchasing. It can be a used vehicle or a new vehicle. Provide a description of the vehicle and the purchase price. Determine the monthly payment in order to buy the vehicle. You may want to use one of the payment calculators used in a previous lesson. Estimate how much you will spend on maintenance and repairs per month on the vehicle. Justify your estimates based on information given in the learning experience or perhaps information you have obtained from another source. Estimate your monthly gasoline cost and justify your estimate using the fuel economy of your chosen vehicle and the calculations provided in the learning experience. How much it would cost to purchase a monthly bus pass. Determine how much you would save by travelling by public transportation rather than using your own…arrow_forward
