Steel construction beams, with an industry designation of "W12 × 25," have a weight of 25 pounds per foot. A new business in town has hired you to place its sign on a 4.0 m long steel beam of this type. The design calls for the beam to extend outward horizontally from the front brick wall, as shown in the figure. It is to be held in place by a 5.0-m-long steel cable. The cable is attached to one end of the beam and to the wall above the point at which the beam is in contact with the wall. During an initial stage of construction, the beam is not to be bolted to the wall, but to be held in place solely by friction.*Diagram Description:*The diagram shows a brick wall with a horizontal steel beam extending 4.0 m outwards. A diagonal steel cable, 5.0 m in length, connects the end of the beam to the wall above the beam.*Questions:*1. What is the minimum coefficient of friction (μₛ) between the beam and the wall for the beam to remain in static equilibrium? - μₛ = [Blank space for answer]2. What is the tension (T) in the cable in this case? - T = [Blank space for answer] N*Reference:*Tipler & Mosca, *Physics for Scientists and Engineers, 6e* © 2008 W.H.

A 2×12 board of airdried Southern Yellow Pine (~12% moisture) is about 2.18 kg per linear foot. A physicist and his wife carry a 16-foot length of Southern Yellow Pine lumber, the physicist gallantly carries the board from one end while his wife carries the board 4 feet from the other end. How much weight is each spouse carrying? This is an equilibrium problem. Assume the board is perfectly uniform.
A tightrope walker stands on a wire that is supported by a pole at each end. The tightrope walker creates a tension of 3.42 ✕ 103 N in a wire making an angle 6.2° below the horizontal with each supporting pole. Calculate how much this tension stretches the steel wire (in cm) if it was originally 16 m long and 0.50 cm in diameter. This question keeps getting rejected as incomplete. This is not incomplete. There is no image to accompany it. This is the entire question. PLEASE stop rejecting it. It is getting incredibly frustrating.

You set up a Halloween prank by attaching a small board to a hinge above your front door. The far end of the board is held up by a cable that can be released by remote control. You place a spooky spider on the board that is dropped on unsuspecting trick-or-treaters when you release the cable. The drawing below shows the set-up. cable 40° Hinge 60 ст You use a board that is 60 cm long and the cable makes an angle of 40 degrees with the board when the board is held horizontally. You place the spider a distance of r = 37 cm from the hinge. The board has a mass of 2.2 kg and the spider has a mass of 1.6 kg. The hinge applies both a horizontal force and a vertical force. You will be asked to determine the direction of both of these forces (left, right, up, down). What is the magnitude of the tension in the cable in Newtons?
