What is the maximum number of people (75kg) that can safely ride in a 600kg elevator? assume it accelerates at 2.35m/s^2 and the tensile stregth of the cable is 25,000N?
The upper end of a wide-skid W 8 × 21 steel column (E = 30 × 103 ksi) is supported laterally between two tubes (see figure). The tubes are not attached to the column and the friction between the tubes and the column is not reliable. The base of the column provides fixed support and the column is 13 ft long. Determine the critical load for the column, consider the Euler buckling in the web plane and also perpendicular to the web plane.

It's a beautiful sunny day and you decide to go fishing for small crappies. Instead a very large curious carp takes your bait and accelerates at a rate of 4.2 m/s^2 when it realizes that it is hooked. You only used fishing line that guarantees a max tensile strength of 25 pounds. What is the maximum weight (kg) of the carp you could catch without snapping the line?
The pole in the figure is a a 90° bend in a power line and is therefore subjected to more shear force than poles in straight parts of the line. The tension in the two wires at the top of the pole is 3.5 × 104 N, and both wires are at an angle of 80° with respect to the pole. The pole is 15 m tall, has an 16 cm diameter and can be considered to have half the strength of hardwood (hardwood has a Young's modulus of 1.5×1010 N/m2 and a shear modulus of 1×010 N/m2). a) First ignore the guy wire (Tgw). Calculate the compression of the pole, in millimeters. b) Still ignoring the guy wire, Find how much it bends in mm to the right. c) Now find the tension in the guy wire used to keep the pole straight if it is attached to the top of the pole at an angle of 30° with the vertical in Newtons. (The guy wire must be in the opposite direction of the bend.)
