Point A is supported by two springs, BC and DE and two cables AB and AD.

Show transcribed image text Point A is supported by two springs, BC and DE and two cables AB and AD. Question 3 25 marks Point A is supported by two springs, BC and DE and two cables AB and AD. Spring BC has a stiffness k = 1500 N/m and spring DE has 300 mm unstretched length. Lengths of cables AB and AD are 700 mm and 800 mm respectively. The structure has the geometry shown in Figure 3 when the vertical downward force at A is 400 N. Assume springs and cables have negligible weights and determine the following: i. Forces in cables AB and AD ii. Unstretched length of spring BC iii. Stiffness of spring DE

Repeat Problem 14.11 using a basement clear height of 14 ft.

Problem 11

Determine the thickness and necessary reinforcement for the basement wall shown in Fig. 14.23. The weight of backfill is 120 pcf and the angle of internal friction is &#120601; = 30∘. Assume a surcharge of 400 psf and use f′c = 3 ksi and fy = 60 ksi.

Design a IO-ft-long, single-angle tension member to support a live load of 49.5 kips and a dead load of 16.5 kips (VD= 3). The member is to be connected through one leg and only one bolt hole will occur at any cross section. Use A36 steel and limit slenderness to length/300. Design by (a) LRFD and (b) ASD.

Two masses m1 and m2 are connected by a massless spring of spring constant k. The spring is at its equilibrium length and the masses are both at rest; there is no gravitational field. Suddenly m2 is given a velocity . Assume that  is so small that the two masses never collide in their subsequent motion. Describe the motion of both masses. What are their maximum and minimum separations?

Using the compass (Bowditch) rule, adjust the departures and latitudes of the traverse in Problem 10.7. If the coordinates of station A are X = 20,000 ft and Y = 15,000 ft, calculate

(a) Coordinates for the other stations,

(b) Lengths and azimuths of lines AD and EB,

(c) The final adjusted angles at stations A and C.

In Problem 10.7

AB = 2157.34; BC = 1722.58; CD = 1318.15; DE = 1536.06; and EA = 1785.58.
