21 k (i) его m 9 Let the position vector for m have the form A particle of mass m is suspended by a spring-pendulum system, as shown on the left. The spring has stiffness k and natural length 1, while the length of the pendulum is also 1, such that the distance between floor and ceiling is 21. The origin is taken to be the fixed point of the pendulum, denoted O, such that OQ = 21ĵ. The system evolves under the influence of gravity, and is constrained to move in the two dimensions of the page. r = lsin (0) Î + 1 cos(0)ĵ. Determine expressions for the kinetic and potential energies. Using a small angle approximation for 0, retain terms up to order 04 to give an approximation for the potential. (iii) Using the approximation for the potential, write down the Lagrangian and compute the equation of motion.

Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the fulcrum how long was the seesaw on Joe's side?
PLEASE WRITE LEGIBLY, COMPLETE SOLUTIONS WITH DRAWING THANK YOU! A car weighing 9 kN travels at 80 km/hr. At the foot of an incline of 10%, the engine stops. Determine: a – acceleration. b – time for the car before it stops. c – distance traveled by the car before it stops.
Q3/ including setting the machine, a worker manufactures 79 pieces of different tools in 7 hours and 15 minutes. If the standard time for the tool was Setting time = 40 min Production time per tool= 10 min Compute: 1-The standard time for manufacturing the 79 tools 2-Efficiency of operator
A CNC milling machine has a purchase price of £120,000 and it is considered from an accounting standpoint to be depreciated to zero value over a period of 5 years. If the machine is to be used for 2 shifts with each shift working for 37 hours/ week and 45 weeks/ year. What is the machine cost/ hr which must be charged in order to amortise/repay the costs over the 5 year period? To make the calculation simpler, you can assume that over the 5 year period you will be required to pay back 8% interest on the sum borrowed. Express your answer in § / hour rounded up to the nearest penny
