Chapter 5, Problem 67P

The compound arrangement of the pan scale is shown. Part A: If the mass on the pan scale is 4 kg, determine the distance d of the 20-g mass to keep the scale in balance. Part B: Determine the horizontal component at pin A. Part C: Determine the vertical component at pin A. Part D: Determine the horzontal component at pin B. Part E: Determine the vertical component at pin B. Part F: Determine the horizontal component at pin C. Part G: Determine the vertical component at pin C.

Answers typed in are incorrect. Tried them many times and they are not right. Please dont give me the same wrong answers marked with a  red X.

mass The power unit A of the tractor-scraper has a mass of 5.9 Mg with mass center at G₁. The fully loaded trailer-scraper unit B has a of 22.7 Mg with mass center at G₂. Positioning of the scraper is controlled by two hydraulic cylinders EF, one on each side of the machine. Calculate the compression F in each of the cylinders and the magnitude of the force supported by each of the pins at H, one on each side. Assume that the wheels are free to turn so that there are no horizontal components of force under the wheels. Answers: F= i H= i 870 1480 1480 11701480540 Dimensions in millimeters 1 KN KN

Find the smallest angle for which the uniform crate can be tipped about corner A. Also compute the corresponding value of P.

The cable carrying three 400-lb loads has a sag at C of hC=14ft. Calculate the force in each segment of the cable.

Problem 6 Compute the reaction forces in B and D. After solving the problem, answer the following question: "Is the force in D directed toward the right or direction? Does it make sense and why?" 8.4 kN f 8.4 kN D 2.8 m 4.5 m 4.5 m left

Hi. Can you please give some advie here to calculate my problems. regards.

A wheel of 10 in. radius carries a load of 1000 lb. a. Determine the horizontal force P applied at the center which is necessary to start the wheel over the 5 in. block. Also find the reaction at the block. b. If the force P may be inclined at any angle with the horizontal, determine the minimum value of P to start the wheel over the block; the angle P makes with the horizontal; and the reaction at the block.

a uniform semicircular rod of radius r is supported on a bearing at its upper end and is free to swing in the vertical plane. The table from the back of the book can be found at the end of the exam. Find: the angle 0 made by the diameter with the vertical for the equilibrium position.
