Nip is the initial gap between extra full length leaf and the graduated length leaf before the assembly.
A
True
B
False
Correct Answer:
True
Nipping is done to balance the bending stress in the full length leaf and graduated length leaf.
A leaf spring consists of 3 extra full length leaves and 14 graduated length leaves. The maximum force that can act on the spring is 70kN and the distance between eyes of the spring is 1.2m. Width and thickness of the leaves are 100mm and 12mm respectively. If modulus of elasticity is 207000N/mm², calculate the initial nip.
A
26.8mm
B
24.9mm
C
22.5mm
D
23.1mm

Select the correct differences between char and varchar data types? i. varchar is non unicode and char is unicode character data type ii. char is ‘n’ bytes whereas varchar is actual length in bytes of data entered in terms of storage size iii. varchar is variable in length and char is the fixed length string iv. For varchar, if a string is less than the maximum length then it is stored in verbatim without any extra characters while for char if a string is less than the set length it is padded with extra characters to equalize its length to given length
A
i, iii, iv
B
ii, iii, iv
C
i, ii, iv
D
iii, iv
You create an assembly by using Visual Studio .NET. The assembly is responsible for writing and reading order entry information to and from an XML data file. The assembly also writes and reads values to and from the Windows registry while it is being consumed. The assembly will be distributed to client computers by using your company, XYZ, intranet. All client computers are configured to implement the default .NET security policy. You need to implement security in the assembly. What should you do?
A
Implement declarative security and execute the permission demand to allow access to the file system and Windows registry.
B
Implement declarative security and execute the minimum permission request to allow access to the file system and Windows registry.
C
Implement imperative security and execute the permission demand to allow access to the file system and Windows registry.
D
Implement imperative security and execute the minimum permission request to allow access to the file system and Windows registry.
