How do you read a micrometer? To read the micrometer in thousandths, multiply the number of vertical divisions visible on the sleeve by 0.025″, and to this add the number of thousandths indicated by the line on the thimble which best coincides with the central long line on the sleeve. What are the four steps […]
Is E coli a cloning vector?
Is E coli a cloning vector? There are many types of cloning vectors, but the most commonly used ones are genetically engineered plasmids. Cloning is generally first performed using Escherichia coli, and cloning vectors in E. coli include plasmids, bacteriophages (such as phage λ), cosmids, and bacterial artificial chromosomes (BACs). What is the size of […]
What is control mass and control volume?
What is control mass and control volume? A thermodynamic analysis of a system can be performed on a fixed amount of matter known as a control mass or over a region of space, known as a control volume. Conservation of Mass. Conservation of Mass, which states that mass cannot be created or destroyed, is implicitly […]
What is the maximum stress concentration factor?
What is the maximum stress concentration factor? A stress concentration factor is the ratio of the highest stress (smax)) to a reference stress (s) of the gross cross-section. As the radius of curvature approaches zero, the maximum stress approaches infinity. Note that the stress concentration factor is a function of the geometry of a crack, […]
Does air entrainment affect concrete strength?
Does air entrainment affect concrete strength? Intentionally entrained air voids improve the resistance of concrete to damage from cycles of freezing and thawing. Any air voids reduce the strength of concrete, with about a 5% reduction in strength for each 1% increase in the volume of air voids. Air voids, however, also improve the workability […]
How the RLC series circuit behaves for the frequencies above and below the resonant frequencies?
How the RLC series circuit behaves for the frequencies above and below the resonant frequencies? How the RLC series circuit behaves for the frequencies above and below the resonant frequencies. For frequencies below resonant frequency, the capacitive reactance is more than the inductive reactance. Therefore the equivalent reactance is equal to capacitive and the circuit […]
What are the factors of difficulties in goal settings?
What are the factors of difficulties in goal settings? Barriers to goal setting and planning could be external and internal factors….6 Barriers to Goal Setting in Organization Inappropriate Goals. Improper Reward System. Dynamic and Complex Environment. Reluctance to Establish Goals. Resistance to Change. What are the three main components of goal setting theory? What is […]
How do you know if a process is statistical control?
How do you know if a process is statistical control? Control charts are used to determine whether a process is in statistical control or not. If there are no points beyond the control limits, no trends up, down, above, or below the centerline, and no patterns, the process is said to be in statistical control. […]
What does a four bar linkage consist of?
What does a four bar linkage consist of? The four-bar linkage is a planar mechanism consisting of four rigid members: the frame, the input link, the output link, and the coupler link. These members are connected by four revolute pairs forming a closed-loop kinematic chain of 1-degree-of-freedom. What are four bar linkages used for? Four-bar […]
What PSI should I get on a compression test?
What PSI should I get on a compression test? 100 psi How many compression strokes should be used during a compression test? 8 compression strokes Is 150 psi compression good? 150 psi is considered a good compression. Low compression is lower than 130. The cylinder should be within 10%. What is the difference between a […]
