Classify the four-bar mechanism, based on its possible motion, when the lengths of the links are: a = 12 in b = 1.5 in C = 14 in d = 4 in Complete solution must be included in the file that will be uploaded at the end of assessment. Input the category type of the given four-bar mechanism in the space provided. For example, "DOUBLE CRANK" or "CRANK-ROCKER" etc. (refer to MODULE 1 for the table with the list of different categories.)True Story! The 1998-1999 Mars Climate Orbiter mission was declared a total loss in1999 as there was a unit conversion mismatch error between Lockheed Martin and NASA. Themismatch was in the thruster force units. NASA used the SI system which called forNewton-Seconds (4.45 times as large) of thrust and Lockheed Martin used Pound-Force Seconds.Calculations placed the Orbiter at 68 miles from the surface as it went into orbit, but it waswithin 57 km of the surface after the breaking maneuver. Any distance from the surface lessthan 50 miles would have caused the Orbiter to crash.a. What was the actual distance of the Orbiter from the surface in miles?b. In percentage, how far off from the calculated 68 miles was the Orbiter?pleassssse solve question 9, statics

Question: A 6-stage-double-suction cetrifugal pump discharges 71 kg/s of oil (SG=0.75) at 1750 rpm with pressure drop of 525 psi. Find the specific speed in rpm. Subject: Fluid MachineriesCourse: Mechanical EngineeringProblem Statement: A car drives on a circular track with radius 270 m. Initially, the displacement s=0 and the speed is 24 m/s. The car then begins to accelerate at At 0.3s (given in m/s? where s is in meters). After 3.4 seconds has passed, determine: (To get this answer you may need to use a table of integrals and/or a numerical equation solver.) The distance traveled: ûn The velocity vector: un The acceleration vector: Be sure to include units with your answers.Hide AnswerTry Another The formula for piston displacement is P = cd2SN, where c is a constant, d is the cylinder bore, S is the stroke, and N is the number of cylinders. For c = 0.7854, d = 3.000, S = 4, and N = 6, find the piston displacement. (Use the rules for working with measurements to give your answer to the appropriate accuracy and/or precision. Note: The values for S and N are exact numbers. Ignore exact numbers when determining the appropriate accuracy and/or precision.)
- Draw the block diagram of a Temperature measurement system .Also identify the names of the functional elements used in the measurement system.Provide a complete solution to the following: A model of Hydraulic Turbine, to scale of 1/5 is tested under a head of 180m and is to run at 500 rpm, at what speed should the model be operatedAnswer. 510rpm Subject: Mechanical EngineeringAim: To conduct a full kinematic analysis and calculate dynamic reaction forces in a linkage mechanism, calculate instantaneous torque, required to drive the mechanism and to present the results of the case study in a clear reporting format. Introduction: Figure 1 shows a pumpjack operating at an oil well. Its representation as a linkage is also shown in Figure 1. The pumpjack is driven by a motor attached to crank OA. A constant torque T is applied to the crank and the crank rotates at a constant angular velocity ???. A force P is applied vertically downwards at the end of the walking beam BD, which has its centre of mass at point G. To design the mechanism, a careful kinematic analysis of the mechanism needs to be conducted. To avoid mechanical failure and to provide adequate support to the mechanism, the engineer needs to analyse the reaction forces in the joints. Masses of links OA and AB are assumed to be smaller in comparison with the mass of BD and are ignored in the analysis.…

[Ch4 - 3] For the hydraulic system (shown in figure), the following data are given: The pump is adding 3.73 kW to the fluid. • Pump flow is 2 x 10-3 m /s. • The pipe has a 25-mm inside diameter. HYDRAULIC MOTOR A0LOAD • The specific gravity of oil is 0.9. • The kinematic viscosity of oil is 100 cS. sTO. ELBOW (1 cS - 10-6 m/s) • The elevation difference between stations I and 2 is 6 m. PUMP ELECTRIC MOTOR VENT ELEVATION OIL LEVEL • Pipe lengths are as follows: pump inlet pipe length = 1.5 m and pump outlet pipe length up to hydraulic motor 5 m. The pressure at the oil top surface level in the hydraulic tank is atmospheric (0 Pa gage). Find the pressure available at the inlet to the hydraulic motor (station 2).1–2. Figure C1.2 shows a mechanism that is typical in the tank of a water closet. Note that flapper C is hollow and filled with trapped air. Carefully examine the configuration of the components in the mechanism. Then answer the following leading questions to gain insight into the operation of the mechanism. 1. As the handle A is rotated counterclockwise, what is the motion of flapper C? 2. When flapper C is raised, what effect is seen? 3. When flapper C is lifted, it tends to remain in an upward position for a period of time. What causes this tendency to keep the flapper lifted? 4. When will this tendency (to keep flapper C lifted) cease Plz connect me if you want to explan subject for me .... +962 79180149 Thx
