The coefficient of friction everywhere is 0.30. If max force P at static equilibrium is 55N, find the mass of the ladder in kg. B 4 m P -3m- The following is repeated as a reminder: Digits will go in the first blank Order of magnitude will go in the second blank (DO NOT type the E) Units will go in the third blank Input one of the following units EXACTLY: N, Ibs, kg, slugs, ms, tus, N-m, Ib-ft, Nim, J, deg, unitless

Please help. Written on paper not typed on computer or keyboard please. Need help on all questions. Please include all units, steps to the problem and information such as its direction or if it is in compression or tension. Thx.

The property data for a steady state vapor-compression refrigeration cycle with refrigerant 134a as the working fluid are given in the table below. The refrigeration capacity of the cycle is 9.4 tons and the refrigerant mass flow rate is 12.4 kg/min. Determine the net changes in flow exergy rate of the refrigerant passing through the evaporator A (Ed) evap and condenser A(Ed) cond, both in kW. Let po = 1 bar, To = 24°C.

A piston engine in which the bore and stroke are of equal dimension is referred to as a "square engine". An 8-cylinder square engine has a displacement of 305 in3. What is the bore and stroke? Round to the nearest thousandth of an inch. "bore" is the diameter of a cylinder, and "stroke" is the height of a cylinder (the distance the piston travels in one stroke). You will need the formula for the volume of a cylinder to solve this problem.

I need these three parts answered, if you are unable to answer all three parts please leave it for another tutor to answer, thank you.

Please solve carefully , Important.

Fill in all blanks before submission. Round the answer to the nearest integer The figure shows a rod of length 6 ft and weight 100 lb hinged to the ground at point A. The rod rests on a stone in the shape of a sphere of radius 3ft. The center of the sphere O is located at a distance of 5 ft from point A. The normal reaction N between the sphere and the rod is lb. The horizontal component of the reaction at A is lb while the vertical component of the reaction at A is lb. 6 ft The magnitude of the reaction at A is lb. The angle of the reaction at A is 3 ft 0 5 ft
