The 6-kg frame AC and 4-kg uniform slender bar AB of length l slide with negligible friction along the fixed horizontal rod under the action of the 80-N force. Calculate the tension T in wire BC and the x- and y-components of the force exerted on the bar by the pin at A. The x-y plane is vertical.
a. Determine the shear and moment diagram. b. Calculate the maximum normal stress on the top of the beam, on the bottom of the beam and indicate in terms of x its location.
The motorcycle is traveling at 1 m/s when it is at A at the bottom of the ramp. If the speed is then increased at v=0.1 m/s^2, determine its speed and acceleration at the instant t=5s
Vehicles arrive at a toll booth with a mean arrival rate of 2 veh/min (the time between arrivals is exponentially distributed). The toll booth operator processes vehicles (collects tolls) at a uniform deterministic rate of one every 20 seconds. Wh..
Discuss whether shoe A (leather) or shoe B (synthetic) is better for the environment based on the data in the table below. Is it possible to weight one aspect (air, water, land pollution or solid waste) as being more important than anothe
The entrance is square edged, and the elbows are 90o. There is a fully opened gate valve on the suction side and the discharge side, and there is a swing type check valve on the discharge side. Determine the system curve for the pump system.
Determine a composite SCS runoff curve number for a 600-acre basin that is totally within soil group C. The land use is 40 percent contoured row crops in poor hydrologic condition and 60 percent native parture in fair hydrologic condition.
Derive the porosity values for cubic, orthorhombic, and rhombohedral packing of spheres. Include sketches supporting your calculations of the bulk volumes of the unit cells.
A 2:1 natural slope is underlain by a 3-m thick (measured vertically) soil cover over bedrock. Compute the factor of safety by using an effective stress infinite slope analysis with c'=0 and o' (theres a line between that)= 35 degrees for the soil..
A disk spins within an oil-filled enclosure, having 2.4 mm clearance from flat surfaces each side of the disk. The disk surface extends from radius 12 to 86 mm.
Write a note on depth sensor comparison. Focus your idea on detecting uneven pavements on local roads and what types of sensors can be used to detect these.
Write a computer program that generates a sequence of random variables from a normal distribution with mean 5 and standard deviation 2.
Estimate the hourly production and unit cost of rock excavation by drilling and basting. The rock is limestone having a seismic velocity of 6000 ft/s. Trial blasting indicates that 3" holes drilled in 12 ft.
