Problem 448
A beam carrying the loads shown in Figure P-448 is composed of three segments. It is supported by four vertical reactions and joined by two frictionless hinges. Determine the values of the reactions.
A simple supported right-angle triangle truss of 1/2( 5 x 12 ) meter square, is subjected with 50KN and 25KN at the mid-span and top end of the truss respectively. The truss is having two internal members one acting horizontal at the mid-span and the other acting diagonal from support A to joint at a point on the slanted side of right angle triangle.
Taking into account that the pined support is on the right and the roller on the left.
You are required to check the determinant and compute the reactions of this truss.
Problem 447
The truss are joined as shown in Figure P-447 to form a three-hinged arch. Determine the horizontal and vertical components of the hinge force at B and then determine the type and magnitude of force in bars BD and BE.
z1= 4^(e^[(-i)(π/4)])
z2= -5i
z3= 3√3<30°
Note: < is the angle sign. I don't have symbol for.the angle sign in my keyboard.
Solve for:
[z1^(4cos z4)]/log(sub z1)z3
Please help :(
Problem 446
A three-hinged arch is composed of two trusses hinged together at D in Figure P-446. Compute the components of the reaction at A and find the forces acting in bars AB and AC.

A concrete dam of hieght 128 ft. was built in a gorge. One side AB of the gorge slopes at an angle of 60 degrees, the other side CD at 45 degrees. The bases of the dam are horizontal and rectangular in shape. The lower base is 1215 ft. by 152 ft., and the upper base is 32 ft. wide. How many cubic yards of concrete were required?
Powder grain manufactured for the use of the large guns are small cylinders (composed of a nitrocellulose compound) with a number of longitudinal perforations. if each grain is 3/4 diameter, 1 3/4 in. long, and contains 7 cylindrical perforations 1/8 in. in diameter, find the amount of material in single grain.
