Help!!! Please answer all Correctly!!! Please Learning Goal:To describe the shape and behavior of cables that aresubjected to concentrated and distributed loads.Structures often use flexible cables to support membersand to transmit loads between structural members.Because a cable's weight is often significantly smallerthan the load it supports, a cable's weight is considerednegligible and, therefore, not used in the analysis. In thistutorial, cables are assumed to be perfectly flexible andinextensible. Thus, once the load is applied the geometryof the cable remains fixed and the cable segment can betreated as a rigid body.Part ACables of negligible weight support the loading shown. (Figure 1) If W₁ = 8.00 lb, W₂ = 78.0 lb, yB = 6.50 ft,yc =8.50 ft, yD = 3.00 ft, and xc = 2.50 ft, find B.Express your answer numerically to three significant figures in feet.▸ View Available Hint(s)1 ΑΣΦ Η vec?Figure1 of 1УвУсEУрW₁HW₂xB=SubmitPart B Complete previous part(s)< Return to AssignmentProvide Feedbackft

Problem A person is doing leg exercises where a 100N weight linked via a pulley is attached to their heel. Based on a simplified system in which the quadricep muscles are the only active muscle group and can be modeled as a single muscle tension, what is the muscle tension and joint reaction force at the knee necessary to maintain this position. You can assume the quadriceps is attached to the tibia 5 cm below the knee, making a 15° angle with the horizontal. The weight of the leg is 120 N and the center of gravity is 0.35 m from the knee joint, and the length of the leg is 0.8 m. Make sure to draw a FBD of the lower leg. 100N Fm

The system requires that you use a very elastic material but the materials available to you are Material A which has a Young’s Modulus of 210,000 N/mm2 and Material B which has a Young’s modulus of 12,500 N/mm2 Using the deflection and stiffness equation, which material will best suit the job?
Learning Goal: To determine the effects of certain geometric shapes, namely fillets and circular cutouts, on the stress distributions inside a rigid body and to determine the maximum applicable axial force in the same rigid body while considering these stress concentrations. The member shown below is made of steel (oallow = 145 MPa ) that is 80 mm thick. The member is subjected to an axial force P that is applied at both ends. Let rf = 10 mm , w = 120 mm , h = 40 mm , and d = 25 mm

I Review Learning Goal: Part A- Vertical impact To calculate displacement and stresses due to vertical and horizontal impact loads. A 10-kg block is dropped from 1.5 m onto the center of a simply supported beam with a length 3 m. The beam has a square section with side length 6.5 cm. The material has E = 200 GPa . What is the maximum deflection? When an object strikes a structure that responds by deforming in linear elastic fashion, the object comes to rest when the structure has undergone maximum deflection. At that moment, the structure's strain energy must equal the sum of the energies before the impact, including both the object's kinetic energy and its gravitational potential energy. Express your answer with appropriate units to three significant figures. > View Available Hint(s) When an object falls from rest onto a structure, the object's gravitational potential energy is converted into strain energy in the structure. The total strain energy in the structure at the point of…
Learning Goal: To calculate the normal and shear stresses at a point on the cross section of a column. A column with a wide-flange section has a flange width b = 250 mm , height k = 250 mm , web thickness to = 9 mm , and flange thickness t; = 14 mm (Figure 1). Calculate the stresses at a point 65 mm above the neutral axis if the section supports a tensile normal force N = 2 kN at the centroid, shear force V = 5.8 kN , and bending moment M = 3 kN - m as shown (Figure 2). The state of stress at a point is a description of the normal and shear stresses at that point. The normal stresses are generally due to both internal normal force and internal bending moment. The net result can be obtained using the principle of superposition as long as the deflections remain small and the response is elastic. Part A- Normal stress Calculate the normal stress at the point due to the internal normal force on the section. Express your answer with appropriate units to three significant figures. • View…
Drop-load (I)This exercise is part of a series of problems aimed at modeling a situation by progressively refining our model to take into account more and more parameters. This progressive approach is very close to what professional scientists do! context We want to lower a suspended load in a controlled way, so that it hits the ground with a speed whose modulus is not too great. To do this, the suspended load (B) is connected by a rope passing through a pulley to another mass (A), which can move on a horizontal surface. To slow down the descent, we added a spring behind the mass (A). Information The masses of the charges A and B are known.The mass of the rope itself is negligible (very small compared to the loads).The pulley has negligible mass and can rotate without friction.The charge ? is initially stationary and is at a known height h.The surface on which mass A is placed is horizontal.There is no friction between mass A and the surface on which it is placed.The string attached…
