Concept explainers
A rectangular sign over a store has a mass of 100 kg, with the center of mass in the center of the rectangle. The support against the wall at point C may be treated as a ball-and-socket joint. At corner D support is provided in the y-direction only. Calculate the tensions

- Find the internal force system acting on section 3 for the pin-connected frame.arrow_forwardThe figure shows a wire cutter. Determine the cutting force on the wire at A when the 75-N forces are applied to the handgrips. (Hint: The horizontal components of pin forces at B and D are zero due to symmetry.)arrow_forwardThe cable carrying three 400-lb loads has a sag at C of hC=14ft. Calculate the force in each segment of the cable.arrow_forward
- The light boom AB is attached to a vertical wall by a ball and socket joint at A and supported by two cables at B. A force P is applied at B where P = 20i - 14j kN.Note that the reaction force at A acts along the boom because it is a two-force member. Calculate the magnitude of the reaction force at A in kN.
