Solution for The smooth uniform rod AB is supported by a ball-and-socket joint at A, the wall at B, and cable BC. Determine the components of reaction at A, the…
A uniform, horizontal, rigid shelf CD has a weight of 40 N and length 1.6 m. It is resting on two thin brackets A and B which are 0.4 m and 0.2 m respectively from C and D, as shown in the diagram above.
Apr 22, 2019 · A steel rod of length 2l, cross sectional area A and mass M is set rotating in a horizontal plane about an axis passing through the centre. If Y is the Young’s modulus for steel, find the extension in the length of the rod. (Assume the rod is uniform.) An equilateral triangle ABC is formed by two Cu rods AB and BC and one Al rod.
Jul 03, 2014 · A thin, cylindrical rod = 20.4 cm long with a mass m = 1.20 kg has a ball of diameter d = 6.00 cm and mass M = 2.00 kg attached to one end. The arrangement is originally vertical and stationary, with the ball at the top as shown in the figure below. The combination is free to pivot about the bottom end of the rod after being given a slight nudge.
A block of mass 3 kg slides down an inclined plane at an angle of [latex]45^\circ[/latex] with a massless tether attached to a pulley with mass 1 kg and radius 0.5 m at the top of the incline (see the following figure). The pulley can be approximated as a disk. The coefficient of kinetic friction on the plane is 0.4.
