A steel cable to be used in a suspension bridge (loaded in tension) must support a weight equivalent to 1500 kg. If the elastic limit of the steel to use is σy= 1380 MPa, y and the UTS = 1550 MPa, calculate:
a) Minimum diameter of the cable to avoid failure.
b) How this diameter must be modified if a security factor of 2.5 is used.

A steel cable with a yield strength of 35 ksi is used to support a load of 10000 lb. Select the diameter of the cable using a factor of safety of 2.5. A standard steel specimen having a diameter of 0.502 in, and a gauge length of 2.00 in is used in a tension test. At 6000 lb the deformation is recorded as 0.00212 in. The load at the yield point is 7130 lb and the ultimate load is 11520...
4) [10 marks] A steel cable is being used to hoist a load of mass Mload 3.3 metric tons through a vertical height L. The steel cable has mass density p 7600kgm3 and tensile strength S-2.5 x 108 Pa. For safety reasons, the stress in the cable (that is the force per unit area) must not exceed Smax - 0.8S. In this question, the mass of the cable cannot be neglected . First assume that the cable has uniform cross-sectional...
A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
summatize the following info and break them into differeng key points. write them in yojr own words apartus 6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
1. According to the paper, what does lactate dehydrogenase (LDH) do and what does it allow to happen within the myofiber? (5 points) 2. According to the paper, what is the major disadvantage of relying on glycolysis during high-intensity exercise? (5 points) 3. Using Figure 1 in the paper, briefly describe the different sources of ATP production at 50% versus 90% AND explain whether you believe this depiction of ATP production applies to a Type IIX myofiber in a human....
