Explanation:
Science is the body of knowledge that explores the physical and natural world. Engineering is the application of knowledge in order to design, build and maintain a product or a process that solves a problem and fulfills a need (i.e. a technology).
Answer:
(C) 29°
Explanation:
ACME THREAD ANGLE : it is the angle measured between the thread axis and thread the thread flanks, with the help of thread angle we calculate the shape of screw thread it is the mean of v thread and square thread the acme thread angle is denoted by β every thread has its own charactersistics which depends on the pitch and diameter of the thread
Answer:
A pigtail when wiring is technique that is used in connecting a lot of wires together.
Explanation:
A pigtail is a wire that is short in length. It has two ends. One end has a connector while the other end has other wires connected to it.
Pigtail when wiring is the connection of more than one wire in a circuit to another device. Pigtail when wiring helps to extend the length of the wire in a circuit if the wire used it short).
Pigtail when wiring is a technique what helps to keep the circuit organised because it prevents the wires from getting tangled.
Answer:
a. 78.4 pieces/hr
b. $0.1806/min
c. $1.34/piece
Explanation:
(a) With a cycle time Tc = 45 sec = 0.75 min.
Production rate, Rp = 60/0.75 = 80 pieces/hr.
Let us factor in the 98% proportion uptime, so Production rate, Rp = 0.98*(80) = 78.4 pieces/hr
Quantity of product annualy = 6000 *(78.4) = 470,400 pieces/yr
(b) Equipment cost rate, Ceq = 500,000(1.30)/(60 x 10 x 6000) = $0.1806/min.
(c) Cost per piece of mould, Ct = 100,000/1,000,000 = $0.10/piece
Cost rate of labour ,CL = 18.00(0.20) = $3.60/hr = $0.06/min
Conclusively, cost per piece, Cpc = 1.20(0.88) + (0.06 + 0.1806)(0.75) + 0.10 = $1.34/piece
Answer:
Option A
60 pH
Explanation:
For series connection of inductors, the total inductance is given by 
where the subcripts denote various inductors
For this case, inductance will be 10 pH+50 pH= 60 pH
