Question 2: The crane's arm has a pin support at A. The hydraulic cylinder BC exerts a force on the arm at C in the L.. direction paralled to BC. The crane's arm has a mass of 200kg, and its weight can be assumed at a point 2m to the right of A. If the mass of the suspended box is 800 kg and the system is in equilibrium, what is the magnitude of the force exerted by the hydraulic...
Problem 2. The excavator bucket and its contents have a total mass of 800 kg with center of mass at G. Neglect the mass of the other components. Your solution must include clearly-drawn free body diagrams. (a) Determine the magnitude of the force in hydraulic cylinder CD and statee if it is in tension or compression. (b) Determine the magnitude of the force in hydraulic cylinder AB and state if it is in tension or compression. (c) Determine the magnitude...
32 The uniform 100-kg crate is supported by the thin homogeneous 20-kg platform BF and light support links whose motion is controlled by the hydraulic cylinder CD. If the cylinder is extending at a con- stant rate of 150 mm/s when e magnitudes of the forces supported by the pins at B and F. Additionally, determine the total friction force acting on the crate. The crate is centered on the 1.8-m platform, and friction is sufficient to keep the crate...

An object of mass -20 kg is lifted by a standard man with the aid of a pulley, as shown in the figure below. The upper arm is held vertical and the lower arm has an angle of θ·33° with the horizontal. The label c.m. marks the centre of mass of the lower arm. Consider the force due to the weight of the object M, the weight of the lower arm and hand, the tension due to the triceps muscle,...
A 100 kg nonuniform boom, 6.0 m long, is loosely pinned at the pivot at P. A 700 kg block is suspended from the end of the boom at A. The boom forms a 30 degree angle with the horizontal, and is supported by a cable, 4.0 m long, between points D and B. Point B is 4.0 m from P, and point D is 4.0 m above P. The center of mass of the boom is at point C,...
A small particle has charge q and mass 2.00×10-4 kg. It moves from point A, where the electric potential is VA = +400 V, to point B, where the electric potential is VB = +800 V. The electric force is the only force acting on the particle. The particle has speed 5.00 m/s at point A, and a speed of 4.25 m/s at point B. What is the charge of the particle q?
A bucket crane consists of a uniform boom of mass M - 201 kg and length L- 59.09 ft that pivots at a point on the bed of a fixed truck. The truck supports an elevated bucket with a worker inside at the other end of the boom, as shown in the figure. The bucket and the worker together can bc modclcd as a point mass of wcight 195 Ib locatcd at the end point of the boom. Supposc that...
Problem 2 The railway has a crossing gate with a mass of 200-kg gate arm located at the center of s at G. The raiway also have a counterweight of 400-kg located at the center of mass at Gw. Find the resultant moment at point A. -2.5 m Ga 0.75 m 0.5 m m 0.25 m
A bucket crane consists of a uniform boom of mass M- 205 kg and length L 59.73 ft that pivots at a point on the bed of a fixed truck. The boom supports an elevated bucket with a worker inside, as shown in the figure. The bucket and the worker together can be modeled as a point mass of weight W 195 lb, located at the end point of the boom. Suppose that when the boom makes an angle of...
