Q5 / In stiffness-limited applications, it is elastic constraint: it limits performance. In strength-limited applications, deflection is acceptable provided the component does not fail; strength is the active constraint. Derive the material index for selecting materials for a beam of length L, specified strength and minimum weight. For simplicity, assume the beam to have a solid square cross-section t x t. You will need the equation for the failure load of a beam. It is below

What did I do wrong?
Hi I needed help with this question. As shown in the figure below, a uniform beam is supported by a cable at one end and the force of friction at the other end. The cable makes an angle of ? = 30°, the length of the beam is L = 2.00 m, the coefficient of static friction between the wall and the beam is ?s = 0.600 and the weight of the beam is represented by w. Determine the minimum distance x from point A at which an additional weight 2w (twice the weight of the rod) can be hung without causing the rod to slip at point A. X=?

Here, treat the large black ball in the diagram as the load. Use the applet to help calculate both the torque due to the crane's weight and the load.
The following forces are acting on the bracket below. The bracket has a width w of 2 inches and a height h of 3 inches. The bracket is in equilibrium (not accelerating). Determine F3y knowing F1x-98 lbf and F1y=195 lbf. For this question, what is F3.y in Ibf? Note that the y- direction is pointing up, so if the force is pushing down on the bracket, it has a negative magnitude. 39

1. The figure below shows the normal configuration of the head with proper posture. The center of mass for the weight of the skull is labeled W and the muscles that attach to the back of the skull are labeled M. Assume all quantities are correct to 2 significant figures. M W a) Determine the mechanical advantage of the skull muscles when d₁ 20 mm and d₂ = 26 mm. Hint: Which force on the fulcrum (rotation point) is the effort, and which is the load? Enter to 2 significant figures Mechanical Advantage: b) Improper posture and positioning of the head can lead to muscle tension headaches. If the head begins to shift forward while studying or reading, the center of mass moves further from the fulcrum or pivot point. It is a subtle change, but the figure below shows the head shifted forward. The center of mass for the weight of the skull is labeled W and the muscles that attach to the back of the skull are labeled M. Determine the new mechanical advantage of the skull muscles when d₁ = 16 mm…
