Learning Goal: To describe the shape and behavior of cables that are subjected to concentrated and distributed loads. Part A Structures often use flexible cables to support members and to transmit loads between structural members. Because a cable's weight is often significantly smaller than the load it supports, a cable's weight is considered negligible and, therefore, not used in the analysis. In this tutorial, cables are assumed to be perfectly flexible and inextensible. Thus, once the load is applied the geometry of the cable remains fixed and the cable segment can be treated as a rigid body. Cables of negligible weight support the loading shown. (Figure 1) If W, = 85.0 N , W, = 510 N, YB = 1.40 m, yc = 2.80 m, yp = 0.700 m, and zc = 0.850 m, find zg.

Parts a and b were answered in a previous question, part c was unanswered this is the entire question :)

Please answer the 4th question

As an engineer responsible for monitoring works in the area of ​​mechanical systems, you must evaluate the following situation: a large client in the retail area has a refrigeration system where it stores some chilled or frozen products to be sold on the sales floor.Recently, the customer's maintenance department has been questioning the system's performance and requested an evaluation of the system's behavior. You went to the location and requested some information from the maintenance manager about the system, who provided the following data: - The system operates with R-134a refrigerant;- The refrigerated environment is maintained at 0°C and the external environment at 26°C;- The refrigerant flow rate in the system is 0.08 kg/s; In addition to the data provided, you carried out some tests and measured the temperature of the refrigerant fluid at some specific points in the system, such as the compressor inlet and condenser outlet, finding values ​​of 0°C and 26°C respectively.…

Learning Goal: To learn to apply the method of joints to a truss in a systematic way and thereby find the loading in each member of the truss. In analyzing or designing trusses, it is necessary to determine the force in each member of the truss. One way to do this is the method of joints. The method of joints is based on the fact that if the entire truss is in equilibrium, each joint in the truss must also be in equilibrium (i.e., the free-body diagram of each joint must be balanced). Consider the truss shown in the diagram. The applied forces are P₁ = 630 lb and P₂ = 410 lb and the distance is d = 8.50 ft. Figure 1) 1 of 1 A E 30° d B D P₁ 30° d C

FINALS ASSIGNMENT IN ME 3215 COMBUSTION ENGINEERING PROBLEM 1: A Diesel engine overcome a friction of 200 HP and delivers 1000 BHP. Air consumption is 90 kg per minute. The Air/fuel ratio is 15 to 1. Find the following: 1. Indicated horsepower 2. The Mechanical efficiency 3. The Brake Specific Fuel Consumption PROBLEM 2: The brake thermal efficiency of a diesel engine is 30 percent. If the air to fuel ratio by weight is 20 and the calorific value of the fuel used is 41800 kJ/kg, what brake mean effective pressure may be expected at S.P. conditions (Standard Temperature and pressure means 15.6°C and 101.325 kPa, respectively)?
