Compute the maximum acceptable tensile service load for a single L6x4x3/4 angle. The service live load is three times the dead load. The 4-in leg contains a single line of 7/8 inch diameter bolts, and the 6 inch leg contains a double gage line of 7/8 inch diameter bolts. Assume no stagger in the bolts, and that all bolts participate in carrying the load (i.e., both elements are connected).
Two smooth circular cylinders of weight w=500N and radius r=200mm are connected at their centres by a string AB of length 600mm and rest upon a horizontal plane.
Determine the purchasing power 3 years from now of an investment of $20,000 today. The investment is earning a market interest rate of 8%, and the inflation rate is 3%.
design a horizontal curve for a two-lane road. The road has 12-ft. lanes. Due to expansive excavation, it is determined that a maximum of 34 ft. can be cleared from the road's centerline toward the inside lane to provide for stopping sight distanc..
The two outer bars (material A) are identical. The cross- sectional area of the middle bar (material B) is 31.544% larger than the cross- sectional area of one of the outer bars. Also, the modulus of elasticity of material A is twice that of mater..
Rod AB is bent into the shape of a circular arc and is lodged between two pegs D and E. It supports a load P at end B. Neglecting friction and the weight of the rod, determine the distance c corresponding to equilibrium when a = 43mm and R = 143mm..
A 6-ft range pole is set over a station on which a sight is to be made with a the odolite. If the sight is made to the center of the rod 4-ft up from the ground, and the center of the top of the pole is out of plumb 0.12 feet in a direction normal..
The motion occurs in the horizontal x-y plane. Determine the velocity V2 of the particle at the end of the 3-s interval.
A balloon is being inflated at the rate of 15m^3/min. At what rate is the diameter increasing after 5 min? Assume that the diameter is zero at time zero.
a 1 meter diameter cylindrical mass is connected to a 2 meter wide rectangular gate. the gate is to open when the water level drops below 2.5 meters. Determine the required value of the mass of the cylinder in kgs.
The elevation of the lowest bottom of the structure is at 1470 feet. Calculate the maximum length (feet) of the parabolic curve required to meet the given conditions.
Draw the shearing force diagram and the moment diagram of the following problem. The beam is indeterminate. You need to integrate the moment twice to get a formula for the deflection v(x).
The defender had a first cost of $300,000, but its market value now is only $100,000. It has chargeable expenses of $120,000 per year and no expected salvage value. To simplify calculations, assume that SL depreciation was charged at $60,000 per y..
